hey B... 6 x 10 is fine....put the bikes in sideways with the handlebars turned it will fit fine...a buddy/s of mine doesn't use chocks at all as the front tire is wedged up against the wall. but he does have that track system that allows you multple places to put your straps...seems to work fine
I'd buy the ratchet style hold down straps at the local hardware store...that way you can load and unload yourself....I think 12 bucks a set...
