How do these trucks fair with the basics? Top speed, fuel consumption, reliability, parts availability? I want something that can handle driving on the highway to work every once in a while so 50-55 mph is a must. And something that I can take to different rallies and MV events on the east coast and the mid west. I'm sure this is not a daily driver canidate but how hard or much can they reasonably be driven in the real world?
Top speed stock is usually 50 mph. Fuel consumption is between 6 and 8 mpg stock. Reliabilty is dependant on the actual condition. Going through your truck yourself, if you're skilled, is fun and relatively inexpensive. Having someone do it professionally is expensive and even more expensive. Parts availability is not an issue, however, some parts and accessories are becoming very high priced. Winch setups complete are over $1,500 now for components in good shape. Brakes, if properly rebuilt and maintained, are very satisfactory. If you're not opposed to modifying the truck, there are a world of options. Engine conversions, disc brake conversions, and the list goes on and on. I have run both 9.00-20 and 11.00-16 tires (currently both of mine are on 11.00-16's) and have really nice driveability with them. Some folks have run 9.00-20's with a stock truck and have no problem getting to 60 mph and with good brakes have no problem stopping. They are at sea level so the engine is running at top horsepower. IMH(humble)O, the M37 is the best all around vehicle available today, and yesterday. I've owned Jeeps (including M715's), many 2 1/2 Deuces, 5 Tons in both 6X6 and 8X8, and a lot of other military stuff but have always had the M37 suit me the best. I found by custom re-upholstering the drivers seat back and bottom I can get the best fit for me in the trucks. I'm 6'4". A thinner seat back can give you a couple of inches more leg room without sacrificing comfort. Proper seat bottom cushion thickness and density can optimize your field of view out the windshield. Both my current trucks (I've owned 28 M37/M43 trucks) run V8's. The 1965 M37B1 4X4 runs a Dodge 318 V8 mated to a stock M37 later style transmission (military NP420) so I can use the stock PTO and winch setup. The 1963 M37 6X6 I built uses a Dodge 360 V8, again with stock B1 series transmission. Both trucks have power steering and an engine driven electrically clutched air compressor. The 6X6 I have recently converted to 12 volts and plan on doing the same to the 4X4 when I get the chance. I would recommend getting a later B1 series, late fifties up through 1968. And if your plan is for a winch, find your truck with one already installed. That'll save some headaches later on.
