Many months ago I made a compartment to store gas
bottles and a fire extinguisher but I never got around
to making a door for it, so today I decide it's time.
I
make a simple frame from RHS then fold some sheet
to skin the frame. I fold the sheet with a 1-inch
return that goes past the frame and over the enclosure,
this won't allow me to hinge the cover but I can cut
out the parts that hit when I apply the hinge.
However
it's such a good fit that I decide to have it push
on rather than hinge. This will allow me to keep the
1-inch fold and help make the thing more weather proof.

The newly made compartment door.

Here's a wider shot showing the compartment,
the left hand fuel tank, and the new wood storage
rack.
Most
motorhomers need to carry some blocks of wood to level
the vehicle for camping on uneven ground, at least
those who can't afford a hydraulic leveling system.
I
have to admit that a mechanised leveling system would
be great, and I almost incorporated one in Wothahellizat
1. However I was glad that I saved the expense and
complexity as after a while I got very good at leveling
with wooden blocks. Also they never broke down and,
apart from that one I left in Port Hedland, never
caused me any grief.
So
we have all these blocks and nowhere to store them.
As some are longer than others it's difficult to come
up with a neat idea, so I cut the long ones so all
blocks are the same length. This makes it easier to
build a storage compartment, and I've chosen to do
so in the hitherto unused area between the body and
the right hand fuel tank.

The wood block storage rack. If the
blocks don't look very wooden that's because they
have steel handles.
One
thing I disliked about the blocks in the past was
that they were difficult to manhandle, so I've added
handles to each block.

A close up of one of the block handles.
This
will make them easier to work with and, as they are
often used to support a jack under the truck, easier
to remove from a position that's hard to reach.

Another job I started several months ago was the installation
of the diesel heater and it's probably time I finished
that off.
It
takes all day to install the air intake and exhaust
pipes and then the fuel line.

The exhaust pipe (silver), and intake
(black). The thin white line is for fuel and the black
one
a wire that controls
the fuel pump.

The exhaust muffler.
I
initially run the heater's fuel line to the truck's
fuel line and T it into that. It's one of the ways
recommended in the installation manual and it seems
the simplest. However we have no end of trouble with
the line sucking air and the heater shutting down
from lack of fuel.
I
also also have trouble with the heater itself, it
starts running then stops after a minute of so.
I'll
sleep on it I think.

When all else fails read the manual. Chris read the
installation manual last night and apparently one
reason the heater shuts down is the voltage dropping
below 10 volts.
I've
just run a small temporary wire to the heater from
my 12-volt source and I did check the voltage before
making the connection, but not while the heater was
running.
I
measure the voltage at the heater while it's running,
sure enough it's hovering around the 10 volt mark.
I beef up the wire and add a spare battery to the
heater's connector to provide a local voltage source.
The
heater works, but still has trouble with fuel so I've
decided to install the spear provided with the installation
kit. To do this I have to remove an inspection plate
from one of the fuel tanks, drill a 19mm hole for
the spear and replace the plate.

The fuel spear in place.
I
also relocate the heater's fuel pump.

The relocated fuel pump. The top loop
in the line is required because the pump is mounted
on the chassis and the heater in the body, and the
two move in relation to each other. The bottom loop
goes to the spear, it provides some strain relief
and means I don't have to use any connectors (ie elbows)
to get around the corner.
The
system is now quite simple with only a few feet of
fuel line.
I
power up the heater but again it doesn't work, there's
still plenty of air in the line though so I try again.
No go. I'm sure the fuel line just needs priming,
and the heater will keep trying by itself, so I get
on with other things.
Sure
enough, several minutes later I hear the heater fire
up.
We
have lift off.

It's now time to install the aerials. There are five
in all, an AM CB, two UHF CBs, a mobile phone, and
a radio aerial. Why two UHF CBs? No particular reason
except that I have the one from the Cruiser and want
to put it to good use, it will become my main radio
with the old one being a spare.
The
first to be done are the aerials for the original
AM and UHF CBs, these aerials used to be mounted separately
but I've combined the mounts this time.
The
mount is a simple plate attached to the roof via a
pivot point, this allows the aerials to fold down
if hit by a tree or something.

Detail of the mount for the first two
aerials.

They simply fold down if hit by anything.
That
was easy, now there's the other three aerials. As
two of them are 1200mm (about 4 feet) long and the
truck is already 3.5m (11.5 feet) high there will
be times when they make us way too high for service
station awnings, low bridges, trees etc. So they must
fold down as well.
Originally
I wanted to use an actuator so I could raise and lower
the aerials from the cab. We already have an actuator
on the TV aerial so it make sense to use one the same.
I spend most of the day building an aerial mechanism
with the TV actuator. It works but has too much play
and I'm just not happy with the setup. Also there's
the fact that we would have to buy another actuator
at a cost of about $200.
I
need a plan B.
Sat
29 Mar
I'm going for a manual fold down mechanism for the
aerials. I'm still not sure if we'll be driving with
the aerials up or down, if it's up then it may be
necessary to lower them if we encounter an obstacle.
Naturally an actuator controlled from the cab would
make this a lot easier, but that is not to be so I
guess we may have to get upstairs if that happens.
As
I will never use the phone or radio while driving
I don't need those aerials to be up, I would like
the large UHF aerial but can live without it. We'll
see how it works out.
So
I have to design a mechanism that allows the raising
and lowering of the aerials and doesn't pierce the
roof panels in any way.

The
roof sheets on the bedroom overhang the main roof
by a small amount, this allows me to make a bracket
that fits underneath the overhang and bolts through
to a top plate and a hinge.
So
far so good, no holes in the roof, but the other end
also needs to be tied down somehow without making
any holes. I make a large plate with a welded bolt
and glue it to the roof, then bolt a length of flat
bar to this plate and over the bracket to form a clamp
that holds the bracket down. A pin on the bracket
and matching hole in the clamp stop the bracket from
moving sideways.

A close up of the clamp.
A
stay is next, it pivots at one end of the bracket
and has a slot along which a bolt on the mount slides.
This bolt can be tightened at any point although I
guess vertical is the only logical option. Some small
handles in the form of short bent pieces of 6mm round
bar are welded to the sliding and pivot-point bolts
and I'm done.

The finished product. Note that the
mount has slots cut into it rather than holes for
the aerials, this makes it easier to remove/replace
an aerial because the wire doesn't have to be threaded
through a hole.

We're slowly decommissioning the Landcruiser and pirating
objects from it to install in the truck. The other
day it was the UHF radio, today it's the "house"
batteries.
The
Cruiser had two 120Ah 12v batteries to run the fridge,
small inverter etc and I've been thinking about adding
them to the battery banks in Wothahellizat.
Currently
we have two banks of 4 x 6v 200Ah batteries, giving
us a total of 400Ah at 24 volts.

The basic system, two banks each consisting
of four 6-volt batteries in series giving 24 volts.
Then the banks are connected in parallel to double
the available current.
If
I add the two 120Ah 12v batteries from the Cruiser
that will bump our capacity to 520Ah. They are different
batteries to the existing ones and you shouldn't normally
add unequal sizes in parallel but as they are all
AGMs that should require the same charging voltages
I'm not worried.
While
I'm at it I want to add some Anderson plugs at the
rear of the truck so I can access the battery banks
directly, mainly to use my 24-volt MIG welder.
And
while I'm on a roll I'll add another Anderson plug
for 12 volts, just in case I ever need it. To do this
I'll tap across two of the 6-volt batteries. Once
again it's not normally the recommended thing to do
but I'll probably never use it, and if I do it will
only be small currents for short periods.

With the extra batteries added we now
have 520Ah.

Here's the right hand bank (the four
blue batteries) with the two Cruiser batteries (the
black ones) on the right. The big white thing is one
of the water tanks. Note the area outlined in red,
this is the motor bike trapdoor at the rear of the
lounge room, a large hole opening directly to the
concrete below that plays an important part in things
in a couple of days.

The Anderson plugs.
As
mentioned I can attach my MIG welder to one of the
Anderson plugs, however the leads are only about three
metres long so if I need to weld something further
away than that, say on the bumper bar at the front
of the truck, I can remove the two 12-volt batteries
and move them closer to the job.
Remember
some time ago I added fuses directly to the battery
terminals?, well that decision paid off big time today.
While finishing off the work on the batteries I'm
tightening one of the bolts on the positive terminal
of the left hand bank when it touches a part of the
steel body, which of course is earthed.
There's
a flash and the spanner fuses to the steel. With the
spanner locked onto the terminal bolt and welded to
the steel frame we're in a world of hurt if something
doesn't step in to help.
I
grab the nearest object and bash the spanner to break
the circuit. The spanner goes flying but then I realise
that the situation was already in hand, the fuse had
blown and stopped the current.

While finishing off some aerial wiring I ask Chris
to get an extension coax cable from the lounge room
in the truck. The motorbike trapdoor at the back of
the lounge is open so there's a large hole in the
floor, it's often like this and we don't pay it much
attention.
She
gets the cable, holds it up and asks if it's the right
one, then disappears without a sound. Immediately
I realise what has happened, she's stepped backwards
and fallen through the hole.
I
rush to the rear of the truck to find her lying on
the concrete, she's shaking and groaning and there's
a pool of blood growing from under her head. If something
similar has not happened to you let me assure you
that it's very distressing to see your loved one in
such a state.
Instantly
my mind goes through all the options, is the head
wound serious?, what about her neck, did she actually
land on that? Who's going to cook dinner?
By
this time Peter and Marie have realised something
is amiss and come around from the other side of the
shed. Marie used to be a nurse so she takes over while
I get blankets and fashion a pillow from a towel.
Meanwhile Peter rings for an ambulance then drives
to the nearest main road to guide them in.
It
quickly becomes apparent that Chris has suffered no
obvious damage and we relax a bit, concentrating on
keeping her comfortable and still until the medics
get here.
They
arrive, check her neck and ask all the normal questions
to see if the patient is lucid, what's your name?,
who's the Prime Minister? etc. We don't take much
notice of the days around here so when asked what
day it is she says that even before
she fell she wouldn't have known that.
Anyway,
to cut a long story short she was very lucky, she
fell backwards about 1.2 metres onto concrete and
suffered only temporary memory loss, looks like she's
done ten rounds with a prize fighter (a very short
one as all the bruises are on her legs), and has a
very sore toe.
I
guess I'll install the cable some other time, I'll
be too busy cooking tonight.

There's still a few things to do before we start the
cladding, and one of the main items is the steps.
These
will store flat under the body, be pulled out, flipped
over, dropped down, and opened up. They will also
be a landing outside the door. All that shouldn't
take long too make.

The steps fold up and slide under the
body, also a landing slides across from being stored
on top of the steps.
I've
also decided to bite the bullet and redo some of the
plumbing. I thought I'd finished the plumbing some
time ago but it's been a bit unreliable.
The
current system should work fine and in fact it's basically
the same system we had in Wothahellizat 1, and that
worked for six years.
But
we're finding that, when left for a long period like
over night, the water seems to drain back into the
tanks and we have to muck around for ages re-priming
the system.
Whether
there's a leak in one of the joins or the check valve
is not working I don't know. Also the control valves
are very difficult to operate and I have a second
pump that I'd like to use, I'll talk more about this
when I get it finished.

Another little job that needs doing is the replacement
of the bolts in an inspection plate on one of the
fuel tanks. There's ten 5mm bolts that hold the panel
on, they're very tight and only have Phillips heads
so it's impossible to apply a lot of torque to undo
them.
Also,
when I screwed them in I wasn't paying enough attention
and the tip of the cordless drill bit snapped off
in the bolt's screw gate and refused to be removed.
I remember thinking at the time that it will be really
hard to get out and hoping that I never have to.
Well
I don't have to, but it makes sense
to fix the problem while I'm here in a nice workshop,
rather than on the side of the road somewhere.
Using
my trusty impact driver I manage to remove five of
the bolts, but the other five refuse to budge and
eventually I just strip the screw gates. I need a
plan B.
Plan
B is to weld some 8mm nuts to the top of the bolts
and then apply the appropriate amount of torque with
a spanner. The welding also has a beneficial side
affect in that it will shrink the bolt, and of course
the heat can often break the bond holding a recalcitrant
bolt.
This
works a treat and before long all the bolts are out.
I
replace them with stainless steel equivalents that
have heads with Alan sockets, these allow the application
of a lot more torque than a Phillips head and should
be easily removable in future should the need arise.

15 Apr
That's it, I can put off the cladding no longer, tomorrow
we'll make a start.
Before
that though I want some photos of the truck in its
unclad form. After much ado in which I first can't
get the truck into gear, and then can't get it to
move even when it is in gear (putting
the transfer case out of neutral helps), I back the
truck out of the workshop.

As you may notice we've got just about everything
we own packed in, partly to get stuff of the floor,
and partly to make sure it all fits.
So
far it does all fit, and we even have a spare cupboard.
