Researching enclosed trailers, used primarily to trailer a 69 Charger RT. From what I've read, if used to simply trailer the car, 8.5 x 20 would be about the minimum size. Most of the trailers I've seen have a side door on the right. With an 8.5ft width is it possible to drive a B body onto the trailer and exit the driver door side? Do you have to exit through the door glass opening? Realize I can install a winch, but trying to keep cost down. Suggestions?
