Sheesh, I'll give $50? Very interested to see what you can come up with DGatz for the rear - I don't have any imminent plans to tow with mine yet, so I'll just see how your R&D goes
. But seriously, to the OP - I concur with the advice here - yes it's rated for 8700 lb, but to me an all-aluminum trailer is a must if towing a big car to allow some carefully chosen cargo - I wouldn't push it any further. Definitely no enclosed trailer with a car on board.
