Some pictures: It's not very stable. Very top-heavy. Let me know what you think in the poll! //karost
If you could somehow shrink the size of the cab down you might be able to make a medium-duty variant of the T-65/75. Perhaps even name it the T-45/55 (After the Chevrolet Kodiak/Topkick Trucks.)
Replace the frame with a H-45, shrink the cab, have the box upfit fit correctly and you'll have an amazing Medium-Duty truck.
