1️⃣🟢The first trailer modification that I made was the flooring. I used 5/8" OSB plywood for the floor. I put three coats of polyurethane on both sides for protection. I used 3/8' carriage bolts to attach my flooring.
2️⃣🟢My number 2 mod was to add waterproof trailer lights. I use my folding trailer for my boat so these were a must have!
3️⃣🟢Number 3 was to upgrade to a 7 blade trailer connector. The 5 pin connector that came with my trailer was not compatible with my 2015 F-150.
4️⃣🟢Number 4 is the custom side rail system that I made. Every utility trailer needs to have a side rail system to strap down various cargo. These rails are made from 2x3's and I used 3/8' bolts with neoprene nuts to build the rails
5️⃣🟢Number 5 was to add a 1,000LB swivel jack. Every trailer needs a trailer jack with a wheel to move it around when its not connected to a vehicle. These trailer jacks are not expensive.
6️⃣🟢My number 6 mod was to ditch the 12" wheels and tires and convert to 13" Carlisle Radial Trail HD trailer tires. 13" rims are easy to find and very inexpensive. Having taller 13" wheels that are rated for 80 MPH instead of 55 is pretty awesome! I used 5mm spacers behind my wheels to keep the tires away from the trailer.
7️⃣🟢My spare tire mounting system allows me to store my spare tire for my folding trailer underneath the trailer tongue. This is convenient both on the road and while the trailer is folded up in storage. I also mounted a four-way lug wrench and bottle jack underneath the trailer floor so that I am always prepared!
8️⃣🟢This modification is arguably the best and most important of all of my mods. The Harbor Freight Folding Trailers FOLDS!!!! Once these trailers fold in half there is no built in mechanism to hold them together. No latch... I made an awesome latching system that safely holds the two halves of the trailer together while in storage and cleverly stows out of the way when the trailer is in use.
9️⃣🟢This simple little mod keeps my license plate out of the way when the trailer is folded up so that I can push it against the wall and the hinge lets the license plate drop back into position when the trailer is on the road. The first time my license place cut my arm is when I took a grinder to the bracket and made this mod!
9️⃣1/2🟢The cheesy plastic caster wheels that came with this trailer fell apart a few weeks after I stored my trailer for the first time. I fought with them for two seasons before I upgraded to the cast iron wheels that are on it now. So worth it!
🔟🟢Upgrading the wheel bearings on this trailer should be a priority for anyone who owns one. I removed and re-packed my bearings on a regular basis because I use my trailer for my boat. Even though I used quality marine grease and re-packed at the end of each season, after four years my OEM bearings were worn out. They are not a quality bearing to begin with.
