1985 Chevrolet M1009 Blazer (look it up)
The M1008/09/10 were a five year ('83-'87) Army experiment to convert existing civilian vehicles into civilian use. They ended up deciding it wasn't as cost-effective as they had hoped, and switched to the HMMWV (Hummer) and other custom options instead.
Some facts:
Front and rear Corporate 10-bolt 3/4 ton axles
6.2L (379ci) Detroit Diesel - this thing is a bit low on power but great on torque and gas mileage, and the power can be fixed by converting a turbo from the later 6.5L Detroit
TH400 (Turbo 400) transmission and a NP208 transfer case, both still shift smooth - transfer case protected by skid plate
10-bolt Gov-loc differential
Warn manual locking hubs
12/24V hybrid electrical system to drive the NATO slave port on the front and a whole mess of comm equipment that it was equipped with at one point
27 gallon tank, with the reported 20mpg fuel efficiency that's around a 540 mile range.
31" Goodyears currently installed

Power nothing except steering and brakes

Manual locks, manual windows, manual rear window, no A/C, just heat and defrost, no radio, no overhead lights, no carpets, just like I like it.
