The Isuzu is a nice platform. With that said, there are a few things to do differently. Look for one with a diesel. They seem to have a better gear ratio. I ended up buying a new ring and pinion from Isuzu, to the tune of $800 but, I got the ratio I wanted. The other thing, I would check out the other platforms, FTR, etc, first, just to see if any of them had a longer rear spring... Just things I would look at if I were to do it again. But, so far, LOVE the braking and the fuel economy. And I don't have the front end done yet. We went camping last weekend and it got 9.4 mpg at 60 mph. I wanted to ask people what is everyone running there rear tires at? I lowered mine down to 75psi, since we done have any water on board or a gen set.
