Isuzu npr 4wd

I'm not sure why you'd put the tanks on the inside, that is valuable space. Mine has 2 tanks, 35 gallons on each side and they're linked. They're insulated, and have heating pads to keep them from freezing. The other benefit to this is having a good balance, and the water keeps the center of gravity low. Having a ton of water sloshing around above the frame doesn't seem great. I put a valve between the tanks too, so in the summer, I can park where one side gets full sun and the other is in the shade. If I want a cold shower, I can just flip the valve to pull from the shade side. Want it hot, reverse it.

My habitat was not self built and was a custom order. (water tanks under the dinette seats)
My habitat mounts 6.5 inches higher than yours on a subframe. (4 inch roof clearance)

I'm not not sure why I, this far into my build decided to look at this forum, but I did a 4wd isuzu and could give you some good recomendations on what to not do. I saw you were looking at 41 vs 37s. I have 40s, and am considering going down to 35. 40s are mostly mud, and are loud AF, and make it crazy high. Also, if you're in lets say mexico, good luck finding a 41 locally. As far as spare tire, make sure you have a good way to get it up there. I used a HF winch on mine and it works great.

For the 4wd conversion, I highly do not suggest doing what I did. Dana 60 front, 80 rear, a 5.38 ratio, and an atlas transfer case. Mine is the gas, which is the vortec v8 with a 4l90 transmission so it was pretty easy to mate, but still a huge pain. Oh, and I did 4 link with coilovers instead of the leaf springs. Also do not suggest. It's cool not but it's a huge pain to get set up correctly.

What's your fuel economy? Mine is the same engine and transmission, but with the Isuzu rear end from the NPR HD.

My wheels are 9x20 super singles, with 37's 12.5 tires
