Like most things I have my trailer was bought as a project, it was a abused 18' goose neck with a 2" dovetail, 5200# axles, brakes on both axles. I installed a steel diamond plate deck, new bushings, new fenders, tires and rewired it. A couple years ago I installed new brakes and hubs. It looks like a$$ as it needs to be blasted and painted but mechanically it's great.

My advice on a new trailer would be as other mentioned, brakes on both axles. Get 5200# axles it's pretty easy to overload a trailer with 3500# axles.
