I seem to have started something with this thread -- unibody vs. ladder frame! Everyone knows that a truck frame is stronger -- but even these frames vary depending on the tonnage of the truck -- Dodge won't even put the Cummins Diesel in the half ton for fear it will twist the frame.
But I get the feeling that some think of the unibody as inherently weak -- like the first ones produced. But they vary also depending on the vehicle - the unibody of the Traverse is made much stronger than the unibody of say, the Toyota Camry. It is hard to get hard facts on what this strength is, but I get the feeling from some of the posts about the unibody is that it has no frame at all, and can be just "pulled apart" by towing. I am going to try to post a couple of pictures below of the frames in question -- they have come from CarFax (being new to this forum, I may fail here!).
The unibody does have a frame - and the factory installed hitch is attached and reinforced to this frame - I guess the question is whether it can withstand the towing of up to 5200 lbs. Chevy says it will.
Owning a truck to pull a small
trailer is not convenient for many families that wish to pull this small trailer - they do not have the seating capacity and some of the other conveniences that a SUV or even a mini-van does. Chevy says it is trying to get into the market of pulling small trailers for families with the Traverse.
Another note: I have heard that Chevrolet, and some other car manufacturers, have considered or are considering using the unibody for their half ton and 3/4 trucks -- I don't think anything has come of it yet other than a persistent rumor that the new Ford Explorer will be unibody.
