Building a Homemade Utility Trailer

This is my dad and I taking a single axel old camper that my Papp gave us as it was on a property he bought for free. The camper was junk but the frame and axel were still solid.
So my dad and I demolished and recycled the camper down to the frame. Then built a Utility Trailer using Treated lumber from Home Depot and tail lights from Tractor Supply.
We probably spent about $300 and a good dozen or so man hours to build it.
