Harbor Freight Folding Trailer Tips & Tricks – Part 2 | Towing Tuesdays!

Last week, on Towing Tuesdays! we looked at four tips to build an all-round smarter, better Harbor Freight Folding Trailer. Here are four more tips to help you with your folding trailer build!

Folding Trailer Cuts

Making it fit

There are three easy steps you can take to make sure you never have to worry about problems folding the trailer at the pivot.

  1. Set your 48″x48″ plywood far enough back (no-brainer)
  2. Turn the screw around so the nuts go on the outside of the trailer (this is contrary to instructions, but go ahead and be a rebel)
  3. Cut out a sliver of the corner by the screws, just enough to let the board rotate without touching the bolt.

Harbor Freight Folding Trailer Carriage Bolts Replacement

Forget the carriage bolts

The trailer uses carriage bolts (bolts with a square shape below the head) to stop the trailer from folding up. This means every time you want to fold and unfold the trailer, you’ll need to use tools.

You can eliminate the need for carrying tools with your trailer by using two trailer pin and clips like this one. You can buy them for a few dollars at your local hardware store. Alternatively, any other thin pin and clevis will do.

Harbor Freight 2x4 Support

Use a 2″ x 4″

Need an extra set of arms, a 2″ x 4″ can come in handy time and again if you’re doing this project on your own.

  • Working on your drilling/bolting/nutting?
    • You can do it the back half of the platform raised to make it easier on your back.
  • Working on your clips and wiring?
    • Having the trailer up is the perfect time to add more clips and tidy up your wiring. Leave a little slack for the trailer to fold without pulling any of your wiring. You’ll be glad!
  • It also comes in handy in helping you prepare to fold your trailer for upright storage, but more on how to fold your trailer in a future Towing Tuesdays! article.

Motorcycle Trailer

Mounting anchors and a motorcycle wheel chock

There’s no sense in building a trailer that you can’t tow motorcycles on. Given that this is a folding trailer build, we’re going to want to keep the equipment as flush as possible so that you can still fold the trailer with ease.

  • Use anchors in four points
    • Use plenty of washers to help prevent wear and pull on the plywood
    • Install the anchors with bolts perpendicular to the direction of the bike
  • Secure a wheel chock in place using wing nuts rather than standard nuts, so that you can quickly tighten and remove them
    • You can also consider drilling two sets of holes for the wheel chock, depending on the lengths of the motorcycles that you’ll be towing.
    • Set up the motorcycle wheel chock at a distance that will balance the weight over the axle.

Leveling Your Trailer

Level your trailer

The tongue of the Harbor Freight Folding Trailer is several inches above the hitch height of my 2012 Jeep Patriot 4×4. As a result I needed to go up to about a 4″ rise hitch attachment, and just like that, the trailer was nearly perfectly level.

You really want your trailer to be as near level as possible.

  • If your trailer tongue is pointed upwards (ball higher than tongue) the trailer will have additional weight on the rear axle.
  • If the trailer tongue is pointed downwards (ball too low), this puts more weight on the tongue, coupler, ball and hitch. The end result is an increase in susceptibility of the trailer tailwagging.
  • A downwards pointed tongue also increases the angle from the ramp on to the trailer bed, which means motorcycles would need additional ground clearance to avoid bottoming out. See next pic.

    Your Harbor Freight trailer is a tilt frame style trailer. You can pull the front a frame pins to lower the rear of the trailer for ease of loading. Yes it will tilt when you load the bike. Have the ramp in place and a helper at hand. Most light to mid weight bikes can be loaded by 2 people. Place ramp and secure in place. Run front wheel onto ramp. Trailer will tip up in front, down in back. Stand on rear of trailer deck and bring bike forward. Your weight will help keep the trailer from tipping forward to soon. By the time it reaches balance point you will likely also be beyond high centering the bike. No it does not always work this way. It also helps to have a Condor style wheel chock to catch the front wheel. Since the Condor has a quick detach kit that mounts almost flush to the trailer floor it is easily removed to fold the trailer for storage. I have loaded a Harley Softail this way.
