Lets talk body/frame swapping

[BR3W CITY]

Overview:

I think that I'm becoming certifiably insane; I need a new daily driver, and was looking to spend up to about $17-19k (late model used). I checked out some H3's since they had room, were 4wd, looked cool, and got almost 23mpg. But thats a lot of money (I buy all cars cash only, payment up front) and would mean that I can't buy a new welder this year....or get more tattoo's.

On the OTHER hand, I could start another build. Sure, my 66 isn't 100% done yet...but its done enough for now. So then I figured, I could just build a classic truck, with some diesel power. I need room tho...so I have to build a CC, XC, or sub/panel truck. But these are damn rare in whole condition.


SUMMARY;
I have contemplated finding (or fabbing if I have to) body and putting it on a 90's turbo diesel 2500 Chevy frame. I know that body mounts will have to be fabbed etc. Anyone done this or thought about it? Ideally, its a way I can build a non-exitant diesel powered 4wd vintage truck, on a modern HD frame.
I can tow my other baby around, look cool, and get near 20mpg diesel.

thoughts? (keep the 6.5td bashing to a minimum, not all of them were GREAT, but for efficiency and reliability they are hard to beat for the cost)
