I understand that this is a bit off topic, and probably outside of your use case (as initially you had noted you DONT want a hitch mount). But just to give you a perspective on what a hitch mount true West Coaster Mountain Biker style hitch mount rack is like this is my truck, I have the BAK Industries MX4 tonneau cover. Again, I am an avid mountain biker and regularly shuttle with my truck. Use cases are different I awknowledge that, but figured you might appreciate another perspective.
I have a friend with a dodge RAM who has a tonneau cover along with a crossrail style mount yakima rack and it works really well for him (it holds two bikes). He cannot unfold his tonneau cover though (its a hard folding cover).
I have a 4 bike North Shore Rack - Again these are geared towards heavy duty usage for us crazy insane mountain bikers ;). They are tough as nails though. No plastic crap to worry about!
