Isuzu npr 4wd

[gator70]

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

Time to engineer a spring mounting bracket design.

Why?
Mount the tank off your subframe... problem solved!

Yes we considered that

But there is a auxiliary fuel tank in that space.

I did some remapping so I'm over 400hp and changed shift points. I'm at 13-15mpg.

How are these trucks on the freeway @gator70 and @elvan ? Considering a ridgerock conversion on an NRR, but I do a TON of highway driving. After conversion is it a feasible highway cruiser? Not screaming at you with high rpms at 70-75mph?

The NRR, I guess the springs are too strong. Mine is a NPR HD.

I've spoke about subframe mounting to composite habitats before. No one cares too much.

I've addressed this in another post.
The issue here is not the subframe, even though the owner suggested that it was.
The tyres and suspension are more likely the cause of the swaying.

Is your speedo calibrated to your tire size?

Yup

Our entry steps, sliding platform has pivoted to this design approach
( trying to maintain a under $500 materials budget)

Looking at the overland rigs on this forum I see these price categories:

1) Weekend warriors (Jeeps, Broncos, Trailers, American pickups)

2) Live aboards (Habitat based - many brands)

3) First Class Travel (Over $400K)



Who can put brands and platforms in each class?

Great build and details / discussion. How was your experience with Roly? I stopped in while passing through Miami and rode in the orange one. That was a while back, thinking your rig may have been there. I also found another conversion company out in southern CA I've emailed but not heard back this week. They use a 4 link front and rear rather than leafs.

Stay as close to stock as possible. Therefore no issues on the trail. My truck is still with those guys. (so maybe it was there when you visited) They are installing a auxiliary fuel tank. I'm patient, still building subframe as we speak.



Note: I can deliver the habitat and subframe installed (turn key) for $60K if you want a Isuzu or Fuso build
