Steve, the trailer dolly # PA66VR needs very little maintenance - just a few preventive steps. Grease the wheel fittings and flange bearings once a year, keep the chain lubricated, and charge the onboard batteries every month or two when not in use. It’s also a good idea to keep the receiver tube and ball mount collar lightly greased for easier coupling. The whole system’s designed for longevity - the motor circuits even have resettable breakers to protect against overloads.

I have personally used this in our demo area, and it's super user friendly and very fun to play with.

How often are you planning to move your trailer - daily, or just a few times each year when moving trailers in or out of storage?
