Which trailer dolly is right for me?
To choose the best parking solution for your trailer, you'll need to know:
- Your trailer's gross weight (GVWR) and tongue weight
- Your trailer's coupler style, including its height from the ground
- The types of terrain you'll be moving on (including grade %)
- If you'd prefer manual, electric or wireless operation
Compare these details to our trailer dollies and accessories, or contact us.

Does each trailer dolly come with everything I need?
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.
What is the difference between gross weight and dry weight?
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.
What is trailer tongue weight? Why does it matter?
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.
