I will also add that I also have a winch mounted inside the trailer. Super winch 3500 that I can use if needed. Once the car is in there and strapped down, it gets a little crowded, but I work around it. I believe I have about 2 to 3 feet in front of the car to move around and about the same in the back if the door is closed. My trailer doesn't have the driver access door, so if I drive the car in I just have enough room to squeeze out of the car, otherwise I pull the car onto the rear ramp door, hook up the winch and pull it in the trailer to the chock for the front tire, strap it down, and reach in and place in park. If I pull it a little closer on the right side a few inches that gives me more room on the driver's side. When I think about a larger trailer and room to take additional items that can't say be mounted on the walls and it takes up floor space and then you end up stepping over stuff. I have the winch mounted, and two chairs folded up in the R/S corner and a small box with fluids, mics stuff on the L/S corner. Little cramped, yes, but I work around it. Driver access door would be a plus in a 20 footer, but I got a deal on mine and its paid for. Only costs I have is a state insp. yearly and new tires every few years, not by wearing them out, but by sitting. Hope this helps.
