TDD 3500 Trailer Dolly
Park small campers and utility trailers with Trailer Dolly Depot’s TDD3500 electric trailer mover. Suitable for ball-mounted trailers up to 3,500 lbs Gross Weight and 350 lbs Tongue Weight. With a variable speed thumb throttle, move up to 1.5 mph in either forward or reverse to park with confidence and efficiency.
A special ball mount adapter provides a secure connection to prevent tipping while connected to your trailer. Interchangeable hitch balls come in 1 ⅞” and 2” diameters, compatible with most small trailers. The dolly includes two pre-installed rechargeable 12V lead acid batteries, boasting 9Ah of use.
Maneuvering the dolly is easy with the 13-inch drive tires, offering grip on multiple surfaces, including concrete, asphalt, and packed dirt. The rear caster wheel provides 360-degree swivel and additional stability, while the foot bar offers more leverage.
The frame is a single, solid piece made from heavy-duty, heat-treated steel. The sturdy square tubing is then powder coated for a sleek and durable finish that will hold up to use and weather exposure.

Move trailers on firm, compact gravel, dirt, asphalt or pavement. Loose surfaces will cause the dolly to lose traction.
