Included with all Ball Mounted Dollies, the Thrust Washer is an optional Adapter designed for Trailers with step-down hitches/lips. See Instruction Manual for details.
The Puzzle Piece can be inserted to increase the height of the Ball Mount to provide more surface area while tightening or removed to bypass any protrusions on the hitch.

What does a proper connection look like?

Yes!Each trailer dolly includes a hitch adapter that's compatible with most ball mount trailer couplers. See the Transformer, Carrier or Accessories page for additional connections. All electric models include batteries, charging cables, hardware and built-in safety features so you can park with confidence.
GVWR (Gross Vehicle Weight Rating) includes the capacity of your trailer (how much you can put in it, including passengers). This is different from the dry weight, or unloaded vehicle weight (UVW), which is the weight of your trailer when empty.
Tongue weight is the downward force that the trailer tongue applies to the hitch when connected to the trailer dolly. Using your Parkit360 for a trailer with too much or too little tongue weight could make moving and steering difficult, or cause issues with traction. We recommend that your tongue weight be 10% of your trailer's gross weight (GVWR), although this may vary for smaller trailers.
If you are not completely satisfied with your Trailer Dolly, customers in the Mainland US and Canada can return their unit up to 30 days after receiving their dolly for a refund, minus a flat return shipping cost and restocking fee.
Parts Only and International Trailer Dolly orders are not eligible for return.
