Choosing the kind of rear access will drastically rely on the cargo you are looking to haul. If you’re going to be hauling a bike, race car or another type car, then a ramp rear door will deliver the best loading and unloading method. Be sure though when buying a trailer with a ramp door that the ramp is spring assisted as one of the important ramp doors can be very heavy. Ramps are also nice for hauling furnishings or other heavy items where you’ll be using a dolly to load and unload them. If you are likely to be using the trailer quite often and will be in and out of it, then a ramp can become rather cumbersome. Enter double door trailers.
