We pull an American Hauler 24 footer with the single walk-through door. It's fine with convertibles, but a little tricky to get in and out of hardtops. Especially for me, 'cause I'm petite!
Kelle handles most of driving on / off the trailer. Just be sure to get a good load-leveling torsion bar setup... it makes all the difference in the world when passing semis on the road. You want the ride to be smooth with your pride and joy in the box!
