We are proud to present the worldâs STRONGEST trailer dolly! With a tongue weight up to 3, 500lb and a newly patented design, wrestling with trailer dollies is a thing of the past. Our dolly is unlike any other, while most other dollies have pneumatic wheels, TRAILER-TUG is equipped with urethane wheels. These wheels absorb shock better than the standard pneumatic tire and are perfect for uneven terrain. They carry two times the load and last up to four times as long. Pair that with powder coated steel, alloy hubs, steel precision bearings, a bumper that eliminates over rotating. TRAILER-TUG will be your most reliable friend. Trailer-Tug comes with a on/off frontal brake. Supports up to 3, 500 lbs of tongue weight, not recommended with a single operator on trailers over 6, 000 lbs. Advisable to have helpers on trailers over 6, 000 lbs. Weight: 54 lbs. 24" L x 20" W x 34" H *HITCH PIN IS INSERTED IN BOX END TAB* | Trailer Tow Dolly
