Building a trailer

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.

 

What amount of weight are you looking at hauling?
I would skip the d44 unless you want a t-case, matched gears and pto on tow rig.
Use front axle spindles m416 axle or a bought trailer axle Save weight.
hydraulic trailer brakes might be the trick if you do run the 44
