How about no big dip or bump necessary for the TC to oscillate like a rocking horse. No concrete highway with expansion joints necessary. Just driving down the road. When I DID hit a big dip the cabover slammed into the cab roof.
What then IS porpoising?
If the TC is securely tied down, and you have decent cab to cab over clearance that is not good at all! Sure sounds like the frame is got some flex going.
