Bought me a new 6x12 open trailer today. My 9 yr. old of the same size needed paint,tires,and I was contemplating a spring assist attatchment as the gate was getting heavy. The new trailer came with the leaf spring assist mounted in the rear under the decking. Works great. The trailer has the grease fitting on each wheel, 2 inch pressure treated decking,and 15 inch tires. And it was $1200 out the door. Already have a buyer for my old trailer.
