Be sure to search on the Class A forum, owners of the Outlaw and Bounty Hunter seemed to chat more over there. Neither seemed very popular, but if it's in good condition and not abused. Plus I'm sure you know what to look for.
Blackdiamond's comment was the one thing that stood out from some previous owners experience though they were riding bikes (Harley/Goldwing style) and they had issues with the bikes getting over the hinge portion. I see that the Spyder has a 4.5" for ground clearance, so I would defiantly check that out.
