Which company do you think designed/manufactured the better of the two frames?

Don't know about Toyota, but Chevy beats Ford in that department. Ford uses a C channel frame, where Chevy uses a box frame. Well, Chevy vans do anyway, I would assume the pick ups use the same frame. I have put trailer hitches on several Chevy vans, and one Ford F150 that I owned back in the early 90's. After seeing the frame of the Ford, I had more confidence in the strength of the Chevy frame.  Jeff
