M36
I always thought the M36s were harder to find and therefore more expensive, but I have been very pleased with the M36. It has a reinforced double frame and we have really taken it to the limit and it has responded favorably every time. The main drawback is reduced off-road capability compared with the shorter M35 (and larger turning radius). We did a manual FWD shift conversion and added 46" super singles on double beadlocks to give us more ground clearance. Prior to the super singles, we tended to drag the rear end when crossing rough terrain. With a full load of 1800 gallons of water, tanks, and pumps, it pushes 31,000# gross. There probably isn't a harder working M36 going right now.
