    Since camping out of a two door Jeep Wrangler sucks (lack of cargo space) and I'm in the market for a roof top tent, I made the long overdue decision that I needed an offroad/camping trailer. I wanted something Expo-style or similar to Boxrocket's trailer but didn't want to spend thousands of $$$ on a prebuilt trailer. I had a 3/4 ton single jetski/PWC trailer that I didn't use anymore, soo I put my building/fab skills to work!

    This is how it looked when I rolled into the garage the night before I got started. The frame measured 46"x33" with a 10 foot total tongue bar length:

    [​IMG]

    The next day, I started by stripping the license plate and trailer lights, pulling the wheels, flipping the trailer over and stripping the old axle assembly.

    [​IMG]

    The original axle assembly wasn't wide enough to mount the 15x10 rims and 33" tires I wanted to run, so it was set aside to have the carrier/hub assemblies removed from the old axle bar. On the good side, I checked the lug pattern with my old stock spare jeep rim, and the hubs just happened to be 5x4.5 bolt pattern, same as my jeeps!

    [​IMG]

    I enlisted the help of CrawlinWJ and his welding skills to help me extend the trailer frame from the stock 33" to 62". This was done with 2"x3"x1/8" box steel. I used 1/8" to match the thickness of the stock C-channel frame. All weld joints were cleaned of paint beforehand of course.

    We determined the balance point on the trailer and set the axle centerline 4 inches behind that to give it a good tongue weight, then we set the spring perches in place, double-checked our measurements, and welded them on.

    [​IMG]

    I then measured the hub-to-hub width on the rear axle on my jeep (approx 58"). We cut a piece of 1.25x.250 round tube, 53" long. We then cut the old hub assemblies and spring mounts off of the old C-channel axle bar, cleaned off the round spindle bars with a flap wheel and slid them into the tube, then did 4 rosette welds on each end to secure them. End result was a hub-to-hub of 58". The spring mounts were then welded onto the new axle tube, and bolted to the springs. Next came the sides:

    [​IMG]

    I went with 6-1.5x1.5x1/8", 18" long for the siderail uprights, with a 2x3x1/8 at front-center above the tongue bar to support the spare rim and tire. Here it is with the axle mounted and side uprights done.

    [​IMG]

    At this point I wanted to test it out, so I borrowed two of the 33" MTRs off my wrangler and hooked it up to my Cherokee for a run around the neighborhood. It tracked straight and is very light!

    [​IMG]

    [​IMG]

    I used the stock 1-7/8 ball hitch for the test but will be getting either a Lock-n-roll or Max Coupler for permanent use. I'll also be reducing the tongue length later on (depending on which hitch I go with).

    The build continues!!:D

    Picked up the steel Friday to resume the trailer build. Today we got on it again, starting with the top rails on the sides. I went with 1'x3''x1/8 thick box for the top rails. The ends were cut to 45 degrees for the corners and welded on.

    I'm using the stock trailer wheels right now just for moveablility

    [​IMG]

    [​IMG]

    Next came the spare tire carrier. For departure angle reasons, I wanted the carrier over the tongue bar. I used a 6" diameter, 3/16" round plate with three lug studs welded into it to mount the tire to. The round spare holder plate is welded to the center upright with a 6.5" piece of 2"x3"x1/8" with two precut 3/16" triangle gussetts for strength.

    [​IMG]

    I used the 33x12.50 spare off my Cherokee for a test fit. The tire just barely sits on the hitch bar, which should keep bouncing forces to a minimum.

    [​IMG]

    [​IMG]

    Here's the trailer hitch system I went with; the Max Coupler :drool: Claimed to be the best offroad hitch system on the market. I ordered it yesterday afternoon so it should be here soon!

    [​IMG]

    I also picked up some 14 gauge sheet for the floor and sides and will be getting on that later today!
