I'm contemplating making a small overland off-road utility trailer for camping and general use. I'm going to go with a conventional 3500lb axle and springs but modified to sit over the axle instead of hanging on it for a bit of lift. Dimensions roughly 5 feet wide x 7 feet long, about 3 foot tall closed box with a carrying/tent deck on top on a 6 or so foot axle, so the track width is close to that of my Nissan. I'd build a swappable tongue with one long one with a kayak carry crossbar on it and a short one with an articulating hitch.
I'm thinking of 2"x3" rectangular steel frame, with smaller steel for the box. I want it sturdy but not too heavy. I'm estimating 11 gauge would be plenty, as that's the same amount of cross sectional steel as 2x3 angle of 1/4" thickness. My big dilemma would be how to construct the panels to enclose the bottom? I could use ~20 gauge sheet steel and Tig weld the seams but that would take a long long time. The thing would be really solid though. I can't think of another good paneling material besides sheet steel or a good grade of plywood. Anything else would be very difficult to work with.
I was going to use hubs that match my Nissan bolt pattern so in theory the trailer and tow vehicle could share tires and wheels.
