The trailer will most likely be made from 2" square tube throughout with eight 2x4 sockets at various points and an aluminum treadplate deck. The axle will be a 3500# with a future option of disc brakes under the 30x9.5" tires on 15x8 wheels. I did some measuring today and the Jeep has a track width of 67.5" from the outside edge of the stock 225/70R15s. When I get my larger wheels and tires, I expect that to increase by about 1.5". The trailer that I've been borrowing is considerably wider, leaving tracks in the sand with a good 2" separation between it's tracks and mine. With that, I'm guessing it has to be somewhere around 20" wider than the Jeep. The trailer I'm designing has a 78" track width, which doesn't seem so bad.
The lateral tubes are 24" on center, making the useful length at 10' 2". The two running lengthwise are 48" on center.
I made the laterals at 24" so that I can order the treadplate in 24" x 48" sections and fit them with as little modification as possible. The outer edges are another story.
The sockets allow me to install a wooden box frame so that when hauling lumber or bricks, I'm not marring something I care about.
For the teardrop, I'm not sure if I'll build it to occupy the full 10' or not. At 5'8", I can sleep sideways and keep some space up front for a cargo box and jerry cans. I probably won't have much of a galley, if I have one at all, although I might change it up a little and put everything in slide-out side compartments. I'm thinking about just having one door on the back and not using side doors at all, making entry more like an APC than a teardrop, but I have time to work that out. The top does need to have a flat spot, or at least flat enough to allow me to attach my safari rack.
