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.
Effortlessly maneuvers utility trailers, bass boats, travel trailers, and teardrop campers in tight storage stalls.
Intuitive thumb throttle offers seamless forward and reverse movement up to 1.5 mph with automatic electric brake.
Solid rubber deep-lug drive tires and heavy swivel caster deliver exceptional grip on pavement, ramps, and driveways.

Ordered the Super Handy Guo041 Electric Trailer Dolly 800W after getting tired of sitting in the dark during Gulf storms. Freight delivery arrived on a liftgate truck right onto my concrete driveway. Hooked it into our manual transfer switch with a 50A cord and ran our central 4-ton AC, two refrigerators, well pump, and all household lights. Electric start fired right up on fuel.
Driver called me 24 hours ahead of time to coordinate delivery. Unit was bolted onto a heavy pallet and wrapped securely. Added oil, connected fuel source, and pushed the start button. Purrs like a kitten and the digital meter makes monitoring voltage and hours simple. Couldn't ask for a better machine at this price point.
The fuel versatility on this Super Handy Guo041 Electric Trailer Dolly 800W was the main selling point for me. Being able to connect directly to propane or natural gas means no more storing 50 gallons of stale gasoline in the garage. Build quality is solid industrial grade and the frame feels bulletproof.
Tested the wireless remote start from about 80 feet away through the back patio door—started immediately. It is surprisingly quiet for an engine of this displacement. Very impressed with the packaging and complete hardware kit included.

It is designed for flat surfaces and gentle inclines up to 4 degrees. Moving heavy trailers on steep slopes is not recommended for safety reasons.
It works well on hard-packed gravel and firm dry turf. On loose deep gravel or soft wet mud, additional traction may be needed depending on trailer weight.
The 12V 7Ah battery provides approximately 1 to 1.5 hours of continuous operation, which is typically enough for dozens of trailer maneuvers between charges.
Yes. As soon as you release the thumb throttle, the automatic dynamic electric brake engages to hold the trailer firmly in position.
Yes. The ball mount has a standard threaded shank, allowing you to easily swap the included 2-inch ball for a 1-7/8" or 2-5/16" hitch ball.
