I use Baxley Sport Chocks for my BMW 1600 GTL, used them for several Harleys, Goldwings and even a Burgman scooter. Never mounted them to the floor, just rolled into the chick and strapped the bikes at front and rear. http://www.baxleycompanies.com/Sportchock.html
We opted for something smaller than a golf cart. We got a Smart Car... :B We cruise the RV park, plus we can head out on the road with it. We do have a toy hauler and load the Smarty in the back.
