Featherlite trailers are awesome! They really weight less than other models with steel frames. So you're starting off properly with that.
The trailer brake wiring harness is properly wired in newer models, so that shouldn't be a big deal anymore.
My trailer is 15'x7'wx7'h. Dual axel with brakes. I have the v nose model, so the flat deck is 12ft and the v'nose adds 3 ft.
I travel everywhere with it; Arizona, Moab, Idaho and soon to be Rubicon!
Here's a pic of it behind the H2. I can get some of it with the Ranger inside and stuff too if you want.
