This is the abs unit.
I did also have to replace my CTIS controller, so it's always possible that plays a role in this.

Been working on habitat prep, doesn't really make for interesting pictures. Will be putting up wood paneling with an unitrut structure on the inside where I can attach all cabinets, beds, etc. Making for a very strong and modular setup.

Took it out on snowy roads for the first time today. Learned a few things.
1. This thing is heavy and doesn't like to stop super well on hills. It will try to swap ends going down hill - got about 30 degrees sideways when rear brakes locked preferentially over fronts. ABS would prevent this (see note below), but then I couldn't get the snow building up in front of the tires.
2. It's more capable on slippery roads than all my neighbors 2wd vehicles that couldn't climb the hills near us.
3. ABS disengages in every mode except HWY on CTIS controller (ABS light blinks). This may be standard but I haven't seen this mentioned before. I did replace the ABS controller so maybe this one is programmed a little different.
4. C7 uses 0.5gal/hr at normal idle, 1.0gal/hr at high idle - per CAT ET
5. C7 warm-up mode with the pac brake doesn't automatically turn off - it will stay on till radiator fand engages

How are you mounting the unistrut/walls to sprayed on insulation walls ?

How are you mounting the unistrut/walls to sprayed on insulation walls ?

Top 4 corners are directly bolted to the box though a thermal break, bottom rails lag screwed to plywood floor, along the 18' length at the top there will be tensioning bolts that go through the foam. Will be very structurally strong and minimal disturbance to the insulation.

These floors are really great 1 1/4 bambo i was told so really good anchoring points i was just curious how you were going to keep the walls straight without drilling thru the sides and top of the box ! I started with a one trip 20 footer as well i hope to see more folks experiment with these things ! Keep up the good work !

I really prefer the shipping container over the fiberglass sandwich stuff. Much tougher, don't have to worry about branches, can mount all sorts of stuff to it due to the strength of the structure. Strong enough to be rollover structure. Steel also seems to just fit better with the military truck ethos.

Yes my thoughts as well when i started looking for a box

There is a world of good information in it...

CHUCKY'S TREE HOUSE !

Just put 5 gallons of 383 on my 1083 camper ! Mixed 4 part 383 1 part laquer thinner and it came out great .There was some concern with the Rapco being to glossy so i used 4 to 1 paint and laquer thinner shot it outside in 80 degree sunshine i shot 5 gallons and not 1 run and thats not because...

Absolutely!
Gotta get yourself a stick to prop up the cab if it decides to fall down.

Its not as common when its new to ya its when you have had it a couple years and you get a little to comfortable then it gets ya !

Tried to start the truck today after it's been cold soaking all night and is -9°F. The two 6TLs just didn't have enough to get it done. No engine preheat and 15w40 oil sure made it more difficult. It would crank for about 10 seconds before voltage dropped too low and starter kicked out. It did cough a couple times with the ether injection.
Batteries are new and fully charged. I bet with a battery heater it could have done it, or if it had the extra 2 6TLs.

Made some good progress the last two days on the interior wood paneling and framing. The interior heats up super fast with my kerosene heater (just one of those freestanding units) and used roughly half a gallon to keep it warm for 12 hours over the past 2 days (it's been a high of 14°, starting off at about zero in the mornings).

Still have more insulation to do as well so that will only get better. Had to keep shutting it off because it got sweaty in there. I did make sure I had a carbon monoxide meter when working and kept the door cracked because I had power cables coming in.

Going for the very utilitarian, but with a little bit of wood to keep it nicer than fiberglass or metal. Give me a break I'm no interior designer.

Made some progress on the pass though. Door for the habitat side is complete (besides sealing and paint). There will be an intermediary box above the filter, then another door/bulkhead on the cab side. The door in the cab will be right behind the drivers seat and can be accessed without having to fold any seats.

Looks like a face:

Installed the cab passthrough door today. Went pretty well. Only concern is how close the coolant tank is, may have to relocate it depending on chassis flex.

 

[aw113sgte]

Welded up the pass though box, .125" so it's heavy but strong. Trusty old Lincoln flux core welder worked great.

If your going to add 24v winches then yeah for sure go back to 4 batts.. (and appropriate alternator). If not doing 24v. winches (or 12) then spend cost of two more batts on a diesel fired coolant heater system. That would more roundly serve your needs IMHO

Like what you're doing. So, this will be permanently affixed to the cargo side and have attachment points to remove for cab tilt? Or will it be removable on both sides? Still curious to see how it will work out.

Not sure about winch yet, but if I do it will probably be electric.
I'm sure the heater would help some, but unless I heated the batteries I don't know if it would be enough. Was considering a 24v jump pack that could be kept warm.
It's a shame alternators are so dang expensive for these trucks.

It will be attached above the air box with bellows on each side, both removable.

they make coolant battery warmers.... or simple tiny car heater core plumbed into battery area
