Isuzu npr 4wd

The St. Andrew's cross is most needed at the point closest to the cabin, where it twists the most.

Thanks for the comment

I'm curious where the comment "twists the most" comes from. I see frame twist from engine mount to rear axle mount. I don't see the twist different along this distance.

Now, when a front wheel is in the ditch, the truck cab leans to that side, while the rear wheels are on level ground.

Now, when the front axle is on level ground and the rear tire is in the ditch, the frame moves down to follow the axle.

Both occur.

Maybe a Fuso frame is different than a Isuzu frame.

I spent the most engineering support on the subframe where the weight is centered in the habitat.

The crew cab has a tube bolted inside the cab from left to right behind the front seats. It is good for commercial use, but not for recreational use.

I did find the picture below. Unsure what the truck is 100%. I guess this tube was removed and custom roll bar inserted. You can see this from the picture.

One builders suggestion where to mount springs

 

[gator70]

When using 12 gauge steel angle, say 4 inch by 1.5 inch. Then creating a picture frame design. Taking the frame and the truck to a body shop and requesting this replaces the rear window width by welding in place, 35 inches in height.

Now I look at a big opening with a "flange" from the 12 gauge angle.

I could cut a rectangle xps panel and use Sikaflex to install it on the flange.

Now I have a nice flat surface to cut the hole that matches my pass-through door currently installed in the habitat.

Here we see the rear window width replacement "frame"

As I stated before we bought a steel rear bus bumper, 84 x 9. Welded two 1/4 tube 2x3 the inside length. We welded a swing away rear spare tire mount. That fits the 84 length, with two hinge pivot points to handle the weight. Then welded a tire tower for a winch mount. Now welded the tire wheel plate for the Isuzu bolt pattern.

It definitely is, as it is not flat.
This is why there is no "one size fits all" solution for kinematic mounting systems.

This spare tire winch design we will copy

Re Crew cab

Does anyone have storage ideas for between two rear bucket seats?

Many builders are moving to high tech electrical

Bluetooth, wifi, managed 12v systems.

Analog is less problematic. Especially when issues occur.

I wonder if this bathroom is too big?

 

[gator70]

I've heard of the battery shut off switch melting and smoking. Should I install a smoke alarm in the electric cabinet?

Not too big, but park on a bit of a slope and the water will pool at one side and then you need to get down on your hands and knees to clean up.
I solved that with my new build....
No "false" bathroom floor. 4 drains with shut-offs and filters for hair. Will handle any slope. The grey water tank is immediately under the bathroom and kitchen sink. OGO composting toilet, HWS calorifier within 500mm of the shower and the kitchen sink.

ps... the bathroom will get a sliding window so it can be left slightly open while driving. Then the heater can run from the engine waste heat and the bathroom (with its own heater outlet) can be a very effective cloths drying room.

Maybe you should size all of the cabling and switch gear appropriately, reducing the possibility of overtaxing any single component of the electrical system.
That's how any decent electrical system would be designed.
