0mpilchfamily 8 years ago Its not a good idea to use the trailer ramp as an extension on the trailer. Doing so would put the trailer off balance possibly causing the trailer to try and tilt back which could force it to pop off the hitch. Most trailer locks won't be able to put up with that kind of continued strain. They are made to prevent the trailer from coming off the hitch when you hit bumps in the road. If you need to haul longer loads then buy a longer trailer.
