I picked up a heavy duty HF trailer for $319.
Having a 2000# axle with 5 bolt hub made a good choice on the HF trailer as it came with the same 5 bolt rims in a 12 inch rim keeping the trailer lower to the ground.
I started on the trailer and did like the short tongue so I moved the mount forward 6 inches.
I will also add a small 3/4 inch square tube from the hitch back to the second cross member and plan to use it to additionally run my wire harness back. Welded in will add additional tongue support to the A frame.
Next step was to widen the spring supports out to 5 foot and I cut the angle iron at 5 foot and then it was a tight fit and likely should have been 5 foot and 1/4 inch but it welded up just fine.
I put the axle above the spring as the axle had the slight arch, and cut the notches in the spring support.
So much more to plan out and calculate as the build goes. I checked on some 1/2 inch plywood with a finished side at 30 bucks a sheet and thinking I need 4 sheets (2 bottom 5X9 and 2 side 4X10) will do it and with a nice spar urethane finish will look good......
