From Erik:
"The door isn't bolted shut. The piano hinge started to break and can't be welded. So I installed a CJ hood hinge to add support so it wouldn't tear off on our last cross country trip."
Aprox. 50k miles on the white GA trailer 3 years, many of those miles maxed out on weight.
I would buy another GA trailer if that's what budget allowed for, just be careful on weights, tires and speed.
