M.A.X. Truck Remix - Closer Rear Axle

I modified https://www.thingiverse.com/thing:3214824 by Somerandomguy03 to have the rear axles closer together. I also cut some off the frame behind the cab to reduce material, estimated print time with my settings showed about a 20 minute reduction, though it was more for cosmetic appeal to me, and modified the muffler stack.

Included are 2 versions for the aft plate, one that is the standard design, and one that tapers in between the wheels that are both shortened for use with this chassis
