LaCross Rookie,
I am in the same boat and have been looking around for the best plans etc. I have not figured out the best way to do it yet.
My plan so far has been to use torsion axles to cut down on the springs etc, but cannot find ones that I think will work for a reasonable price. I keep thinking that a 3000lb axle is not enough for the trailer if I decide to haul a fourwheeler, sled etc. Let me know if you have any ideas about it.
I also want it to look professional and was looking for a local supplier of enclosed trailer parts. I would like to use the hinges, lever brackets for a door on the back as well as an aluminum siding (RV style). If you know of any suppliers of that stuff let me know. Everything I have found is a little more then I want to spend.
Thanks
Brent
