Boat, Utility, and/or Travel Trailer dolly for up to 10000Lbs with 900Lbs on the tongue. Excellent condition. 16" wheel and well kept. Battery not included. One can use the RV battery connection with cable provided or get your own deep cycle battery. Two ways to connect to the trailer. Easy to maneuver . Please note: This is not intended for pushing or pulling on hills. This dolly was used for an 8000Lbs travel trailer to position in tight places. Serious queries please.
