Went today to see this truck. CUCV M1008, originally an un-issued Marine Corp Truck. Drove great, stopped and shifted great....etc
For those who dont know:

6.2 NA Diesel
TH400
4.56 gears

Very little if any rust of the body, typical surface rust on the frame.
Interior is great, new bench and dashpad

22k miles

Started very quickly

No lights worked at all, I think it has to do with the blackout system, but told the guy he needed to fix that before I purchase.

$8750

The setup you have is rock solid but very power inefficient. New Military crate 6.2’s used to be abundant and cheap to source. (If you want to play around, abuse or keep on the road a long time)
I would put it on the list to get a xmbr a hydraulic clutch and an nv3500 (or if your rich 4500). The 3500 is a drop in replacement for the 700r4 so the conversion from turbo 400 to nv3500 is similar to a 400 to 700r4.

These trucks are INFINITELY more enjoyable on the road with a stick and you can gain a fair amount of mpgs and dyno at the wheels can be +50.

It’s rarely talked about but these trucks are easy to tune, advancing timing a bit especially with a gear change and turning up the fuel pump slightly makes the truck peppier and your MPGs go up. You can keep the stock tune if you plan on running the truck as is but you will be spinning 4000+rpms a lot. 6.2’s usually don’t care about extremely high revs but it’s only useful if your towing.

If your gonna drive mostly on the road consider smaller street tires and a different rear axle differential.

Lightly loaded 6.2’s live the longest, if you plan on towing a LOT
turning the fuel pump down slightly and sourcing a c-code intake will make the truck wimpy but it will last forever and get better fuel economy.

With the right gears these trucks will tow anything, just very slowly. If you make a 6.2 tow fast it won’t live long, there were forged steel replacement engine parts (cranks, cradles, etc) but that’s a lot like work

The new seat means "city miles" as there were endless butts sliding in and out, every 1/2 mile.

I wonder about the chain of custody on these, from government auction to the guy you've found it from, with each party adding value, or, perhaps, just price.

Also make sure you get a title. Humvees for example may not.

I work on a navy yard where the vehicles never exceed 20 mph or trips over a mile, except leaving once a month for gas. I wouldn't think twice about the odometer reading but instead use your normal used-car senses to see how whipped the thing is, how tight the steering is, how leaky the powertrain is, etc. We have a POS Transit Connect with 10k miles and a hole in the rubber "carpet" under the pedals down to rusty floorpan already. We joke about running the other way if we see something of ours on govdeals.com.
 
ohhh man. Those burgundy vinyl seats are going to stick to your sweaty skin this hot and humid summer. You'll regret being born if you buy that thing. Some Navy guy probably did unthinkable things in the back of that truck while a Marine watched. Have you seen the stain that a digested MRE leaves on a bench seat? No,,, you don't want that thing.

YOU MUST DO IT!!! I'd love to find one of those that wasn't completely wasted.
 
I like it, if it is as solid as it looks it has many more good years in it. Personally I love the sound and smells of a old purely mechanical diesel.

Can it even do the speed limit? Engine probably redlines at 50 mph. Whenever I pass a convoy of military trucks, they are doing about 45, and even at that speed the engines seem to be screaming.

Even so it can go more than 30 miles before needing a fill up like a used Tesla someone bought. LOL
