We've had a 2 horse straight load bumper pull with a dressing room for almost 10 years now. We bought it used, so it's now past its 20th birthday and still going strong. This year we will need to do some maintenance, but considering it's age, it's awesome. It's been one of the better trailers I've had, for sure.

The quality of the 2h BP Colin-Arndt trailer I looked at while shopping was very good. It did seem cramped inside, but it was an older trailer, too. So if the one you are looking at is sized right for your needs, definitely worth considering.
