Buying Guide: Power Dollies For Boat Trailers
What capacity do you really need? For small-to-mid boats, 3600 lbs to 3600 lbs range models often suffice. For larger boats and RV trailers, 7500 lbs capacity is typically safer. Consider tongue weight as well; higher tongue weight improves stability but requires proper setup.
Which hitch configuration matters? Look for models offering both 2″ and 2-5/16″ hitch balls, or dual-ball setups, to maximize compatibility with your trailer coupler heights.
What about tires and ground surfaces? All-terrain or pneumatic tires improve traction on concrete, grass, and dirt. An anti-tip design helps during turns, especially with longer trailers.
How important is battery life and power? Battery type (lead-acid vs. lithium), motor wattage (800W is common), and runtime influence how often you can move trailers before recharging. Onboard charging compatibility matters for quick top-ups.
Portability vs. stability? Heavier, higher-capacity dollies offer stability for big trailers but require space for storage and more careful handling. Lighter options are easier to maneuver in tight spaces but may underperform with heavier loads.
