How does the jack post connection work?

Instead of connecting to your trailer’s coupler, you can connect directly to the jack post.

Simply remove the Ball Mount Adapter from the dolly to begin. With your trailer supported on jacks or blocks (or connected to a tow vehicle), wheel the dolly underneath the jack post.

Lower the trailer jack into the receiver tube on the dolly. The trailer should rest as close to the dolly’s tires as possible to reduce strain on the jack post. Once the jack is lowered, you can remove your supports and begin moving the dolly.

This connection method works best for trailers with a Gross Vehicle Weight of 8,000-10,000 lbs or with more than 800 lbs tongue weight, but is also an option for any trailer that does not have a compatible coupler.
