Up to 9,000 lbs. Remote Controlled Trailer MoverIntroducing the the RVR Series! Our first self-motorized and remote-controlled series of units, the RVR9 is designed to take the chore out of moving your trailer. With the RVR9 you can now move your trailer without bending over or the need to use your own drill. The RVR comes with a rechargeable lithium ion battery that can give you up to 30 minutes of runtime. The included remote control allows you to not only move your trailer with just the push of a button, but you can do it from up to 40 feet away. Now you can move your trailer into tight spaces without having to ask someone else to help you look around the corners. Heavy-duty caterpillar treads allow the RVR9 to go over different terrains. The RVR9 also comes with 4 planetary gear motors that can drive both single and dual axle trailers. The RVR9 includes the Trailer Valet RVR Base and Ball Set attaching the unit to your trailer coupler. This includes a 2 inch hitch ball and our 2-5/16 inch hitch ball converter.
