So I have been looking for a decent square body for some time now. Didn't really have my eyes on anything in particular, but the frame and body needed to be in as good of shape as I could find.

Last week I came across this beast on marketplace up in Massachusetts. It's a 1986 Chevy M1031. Which is the military CUCV service truck.

It is I'm great shape. Frame is rock solid, and the cab has very, very little rust. It is also mechanically sound. A couple little leaks, but that's to be expected.

It has the 6.2 diesel, th400 trans, np205 t case, king pin Dana 60 front axle with a limited slip, 14 BFF rear with locker, and 4.56 gears. The service body is all aluminum. It used to have a PTO driven generator and air compressor, but those have since been removed. The PTO is still on the t case though.

My plans are to keep it fairly original, but add a few creature comforts to suit me better.

That would be nice of them. I tried zooming in but couldn't tell what the date code on the tires were. But they are obviously used, but I don't see any dry rot either like was on my just 4 year old tires. Were these used in service for a short time and replaced well before needing it? These types of tires specifically have a much longer service life I assume, so you wont be worried about getting good life out of them?
Gotcha, I didn't know if they were different than normal tires or something.

also find those shocks somewhere else and tell them to ship/charge for all but shocks and get this build going
So you'll have it all on by sunday then?
Just giving you a hard time, cant wait to see it put together though. Not a big fan of those wheels and tires by themselves but I am thinking it might look better all together. I was looking through some pictures of similar builds and I think I like it.. still wish you had gone custom flat bed though
Or sell that one for profit to fund the build even more
8-9 years old and no cracks is nice! The tires I just replaced were only 5-6 and were getting rough looking between the treads
Nice, I am liking the tire size and height it ended up at
Seeing it from that angle its missing something and I cant quite tell what.

Also are you planning to keep the inserts in? Do you have too?
Just watched a video and that looks like a royal pita to put the pvc spacer in a tire.

Maybe thats what I am thinking it needs, not sure
Can you be contracted out to plow and make money that way in your area?
I used to have a picture of a gap I filled with tig, hate doing that as well. Ends up looking like a chewed piece of gum.. well several, stuck on there.

How would you know if there is too much or not enough fuel on this setup?
From Eric's thoughts..... How much boost should I put on this? yes

That spool up does sound good
I was trying to find the compressor maps for the wh1c you are running to see where you are at on the map and ran across this. You probably know most of it but might find it useful.

Well you know it’s funny though, I have been questioning “ideal” there’s trade off like you mentioned.. longevity, spool up, etc

You’d think you’d want to be in the ideal range on the map but if you look at all the big names and what setups they are running seems they are all over the maps not wildly but they also aren’t consistently shooting for perfect ideal either. I know we didn’t try for ideal when we sized them for the formula cars
