M-4 high speed gun tractor. ( revised)

Hi everyone. Here's what changed from my last build. Slight change to the track layout, made crew compartment smaller, moved gun to the centre of the roof and increased the size of the rear bays and added tools and a crane. So she is a M-4 now and a pretty sweet one if I don't mind saying so. Ha ha. I just need to build the right kind off gun for it to tow. I was thinking a 105 or 110. I'll just have to see where the buliding takes me. Until next time, have fun and keep building everyone.
