My Off road trailer Build _M416 copy

Ive always wanted a military trailer and had little luck finding one that didn't need to have everything replaced, even states away or across the country it wasn't an easy search, so I decided to build my own. Got the dimensions to the trailer I like, off the internet, and started planning the build. Im a cabinet guy, so the tub is a 3/4" plywood box and the trailer is a HD Harbor Freight 4'x8' folding trailer kit. When complete, the trailer and tub base will measure 41" x 72" and the only change to the dimensions I made is to make the sides 24" high instead of 19" from the military trailer plans. I used the HD trailer kit because it comes with the same lug pattern as my TJ.

My build was inspired by ArmyRn's HF little trailer build thread and jsherbr's design ideas in his Dinoot trailer thread

Ill also be adding a much simpler version of a box, that I recently built, to show how inexpensively a cargo box on a small Harbor Freight trailer can be built for fun and travels

Looks like you are off to a good start. The "cabinet guy" in you shows with clean cuts and tight joints. Look forward to watching the progress. Are you planning on putting 15" wheels on it when you're done? Those HF trailers look like a good buy. Keep us posted.

The trailer is almost complete, it's just now that I'm starting the thread. I called it quits after the third time I had a long post with pictures going up and the "too many users" window came up and lost it all... I may delete the whole thing if they don't fix it.

Very interesting and I'll sub to this thread as well. Don't let the forum server issues stop you from posting smaller bits of the build!

The wide boards for the sides are added after I realized I had nowhere to mount my lid supports, so these are loaded with glue, tacked in place and piled on a lot of weight overnight to press, smear and hold the glue and wood till dry.

In order to keep everything lined up, I cut 3.5" off of each side on the cross bars, originally 48" I needed to cut 7" off for a 41" width. This way all the factory holes would still line up for bolting. The side pieces are 2 - 4" lengths, so it can fold (mine won't anymore) I used 1 full length and cut one down to 2" so when bolted together they'll be 6". They got cut, drilled and I painted the edges of everything after cutting, the Final trailer size will be 41'W x 72"L

Used one of the extra cross bars to make some corner supports, that I will also use as an attachment point to bolt the tub to the trailer.. After adding the gussets to the bottom corners of the tub there isn't any room to get the bolts into the frame, so the corner braces are necessary for mounting the tub.

This is my edge sealing technique, its glue with a little water. Add enough water to thin the glue so it can be painted on, not too watery and not real thick, kind of like a milk shake. 2-3 coats on all edges will make it so the paint won't get all sucked in.

Painted up the Shackles for the new springs, Ill add more about those later. I ditched the stock short 21" slipper springs for aftermarket 28" full shackle set up for a nice ride.

The new weld is the bracket relocation under the front of the trailer. When I narrowed the trailer 3.5" on each side, I also had to move the brackets that hold the front A-Frame, in 3.5"
