HET with moving wheels

Friend drove these in service. thought it would be fun to make one. Found fozzybear made something and decided to expand on it. Created more detail from photos i found of the vehicle. created moving wheels and axels for truck and tailer. I made the ramps move as well adapting hinge by andyosier and use 5th wheel by hugobiermann for a more accurate connection point. All three designs are great and helped me get my final product. I also made a version of trailer neck with the spare tire holder seen in many photos.

Supports
Trailer prints bed down with supports everywhere
Trailer wheels supports on Bed only
Truck prints belly down with supports everywhere
Truck wheels print supports either way.
5th wheel not sure it needed supports.
