10-Minute Tech: Hitch Dolly

A DIY trailer hitch dolly constructed by Bill Vanhook, of York, South Carolina and submitte dto Trailer Life 10-minute tech

As I have gotten older, the trailer hitch ball mount has gotten heavier. So I made a dolly to transport the ball mount to and from the truck. I started with a small dolly that has four swivel casters. I then made a support for the ball mount out of 2-by-6-inch lumber and plywood. The height is calculated so the ball-mount stinger lines up with the receiver. A minor amount of effort is required to slide the ball mount into the receiver or to remove it.

  1. Ingenious! Many times I hitch up the travel trailer and just meet my husband at the campground. The trailer hitch ball mount is a bear to bring out of the garage! This is exactly what I need/want/am gonna get ASAP! Thanks for the inspiration!

  2. I was having trouble too. Because we remove the ball mount when we’re staying somewhere for multiple days, I’m making a transporter from a wood tray attached to a car jack. That way, the height is adjustable. And the tray is removable in case I need the jack for its original purpose.

  3. I copied your cart. I love it. The only trick was to get the height just right to start the hitch into the receiver. Since the cart carries most of the weight, once it gets started, it goes in very nicely. I was able to buy all the parts needed for about $20 and a few scraps from the junk pile.

  4. About the same time as you built your cart, my wife and I were developing the RollinHitch, which makes transporting, installing, retrieving and storing a weight-distribution hitch effortless. It carries all the pieces including the hitch, spring bars and sway brakes while incorporating a chain tensioning tool into the collapsible handle. Please see it In action at http://www.rollinhitch.com. After building and selling them for a while, we’ve decided to get back to our retirement and are now looking for someone to take over the project. Included is a high-quality patent acquired through UCLA’s patent program, which covers all forms of trailer hitch dollies until 2,038, 10 finished and boxed RollinHitches and all building fixtures.
