I built this trailer mover to move our 5th wheel camper into the garage after getting into to many arguments with my wife while trying to back it in with our truck. We sold the camper a year ago and I’ve been using it to move our pontoon boat. This still can be used to move a medium size 5th wheel if that’s what you have. It has two drive motors to drive each wheel independently. Two deep cycle Marine batteries with on board chargers. In it’s current configuration a regular travel trailer won’t work because of the tongue jack being to far forward. I have another idea in mind that will allow this mover to work for that. If interested I will share the particulars . The picture on me moving the 5th wheel was before I installed another motor and second battery. It has only been used on a fairly level paved driveway.
