6x10 Utility Trailer Plans Anyone Ever Owned A Trailer With No Suspension?

Anyone ever owned a trailer with no suspension? - 6x10 utility trailer plans

I recently purchased a program to open 6X10 trailer. Axel has a straight, so that will be displayed by a tractor. I will fix it, but can not decide whether to work through the sweat and suspenstion follow a new fountain. Nothing that a couple of quads and some gear, not to throw too hard.
