There are a few things that i duece will buy you over a 5 ton. The GVW on a duece is no greater then 23,000 or so lbs, 23,530 for a winch truck. This means you are below the magic 26,000 lbs number that a normal class C license covers. Anything above 26k and you will need a higher class license. Not necessary a CDL. Second it is a mulitfuel engine You can get an old M52 tractor the M39 series trucks used the LDS mulitfuel engine. JUST BECAUSE IT SAYS MULITFUEL DOESN'T MEAN YOU CAN BURN ANYTHING. Sorry but I feel that needs to be spelled out. If you clean, filter, PH balance and filter again the "fuel" You can burn a larger variety of fuels. Alot of people don't play chemist and end up ruining injection pumps. third the truck is lighter for all things parts, tires, brake drums, so everything is lighter on a duece. last you will get 8 mpg with a duece. On a 5 ton you are over 26,000 lbs so you will need a higher class license you have power steering and more Hp at your disposal and it is easier to get more power out of the 855 NTC then the multifuel. things are heavy 11.00 x 20 tires make the truck higher but you can run taller tires then a duece and singles are easier to find with the M939 series 14.00 x 20 radial tires out there. The duece you almost need custom wheels A3 wheels are out there but expensive and the 14.5 tires are hard to find and expensive. you only get about 5 mpg max. So some more info to think about.
