I think you mean the Roden M37 3/4 ton truck. The plastic is soft and directions spotty, but it can build into a very nice kit. Def Model does some replacement resin wheels that are nice as well.
The M35 is a 2 1/2 ton truck and made by AFV Club. It is an excellent kit.
AFV Club also does a Vietnam-era M35A1 as the Nancy guntruck. It can be built as an M35A1 cargo truck w/out the .50 cal quad gunmount as well.
