I think the question about the driver's escape door on the left side has been talked to death on previous posts, the doors don't line up with the viper on the floor of car trailers, therefore you have to build a series of ramps and get the car higher in the trailer for this to work...some require about 9 or more inches to get the car up, when you add the extra wood to raise the car, I feel that you add the mortal enemy of any car trailer " More WEIGHT" my $.02
