Rear AccessIf you select an enclosed trailer, next you wish to select either a ramp rear door, double rear doors or one single barn type door. Choosing the kind of rear access will significantly depend upon the cargo you intend to haul. If you’re going to be hauling a bike, race car or some other type car, then a ramp rear door will supply the easiest loading and unloading method. Be sure though when purchasing a trailer with a ramp door that the ramp is spring assisted as one of the important ramp doors can be very heavy. Ramps also are nice for hauling furnishings or other heavy items where you’ll be using a dolly to load and unload them. If you’re going to be using the trailer typically and will be out and in of it, then a ramp can become rather bulky.
