We've had an Pacific Coachworks Econ 16RB since October 2013 and have never had an issue with it. Bought it new and it's never been back for anything. Service the bearings is all that's been done.
I think of them as entry level trailers as they're basic but it sure is meeting our needs. I did add to the base trailer 2 6V batteries and a 2nd propane tank to allow us to dry camp when we want to.
Good luck in your search.
