The SuperHandy GUO041 Motorized Electric Trailer Dolly transforms heavy trailer parking, moving, and positioning into an effortless one-person operation. Engineered for boat trailers, RVs, utility haulers, enclosed cargo trailers, and horse trailers up to 2,800 lbs with tongue weights up to 440 lbs, it eliminates the strain, back injuries, and repeated truck re-hitching of maneuvering trailers by hand. Powered by a high-torque 800W 12V DC electric motor and a sealed lead-acid 12V 7Ah rechargeable AGM battery, the dolly moves smoothly forward and in reverse at speeds up to 1.5 mph. The intuitive ergonomic control handle features a thumb-activated variable speed throttle, forward/reverse rocker switch, battery power indicator, and emergency safety reverse stop button. Constructed with heavy-gauge tubular steel and equipped with dual 8-inch all-terrain deep-tread drive tires and an integrated swivel caster wheel, the GUO041 provides maximum traction on asphalt, concrete, and packed gravel driveways. Comes with an adjustable 2-inch hitch ball mount (height adjustable from 16.7" to 24.5") and universal battery charger.
2,800 lb Towing Capacity: Effortlessly maneuvers utility trailers, bass boats, travel trailers, and teardrop campers in tight storage stalls. High-Torque 800W Electric Motor: Powerful DC electric gear-reduction drive delivers smooth starting torque and precise low-speed parking control.
Variable Speed Thumb Throttle: Intuitive thumb throttle offers seamless forward and reverse movement up to 1.5 mph with automatic electric brake. Adjustable 2-Inch Hitch Ball: Coupler height adjusts quickly from 16.7 to 24.5 inches to match varying trailer tongue heights.
