I am looking to use a spare CJ5 frame to build a utility trailer. I am looking at using a D44 rear axle, putting two sets of springs on the axle for load, and putting a anti sway bar on the rear axle. I am thinking of using a couple of mated tubs to building the box. I'm thinking I'd like a tub length of somewhere between 6' - 8'. I know the tongue length to trailer length is critical. Anybody got any thoughts or can lend assistance? I've tried googling for trailer plans, and well, you get a lot of "free" hits, but most of the stuff lacks detail in build measurements. This will be for hauling stuff, not a camping trailer or a toy hauler per se. Any draw backs to using a D44 rear axle? I know it won't have brakes, and I'm ok with that. I could easily swap that out at some point to get e-brakes. But right now, I want to use what I have available.
