I bought a 24 foot ATC bumper pull in 2011 and picked it up at the factory. Cabinets across the front, all aluminum floor, walk-on roof, uninsulated and not lined. Paid $17K. I considered a Gold Rush but they were over 25% more money for what appeared to be comparable quality.
Contrary to the problems Jeff Jewell experienced, I have not had any problems and am very happy with my ATC trailer. The aluminum frame on an ATC is hell for stout. I bought my trailer through Bob Resner in Duncan, Oklahoma. He was very helpful offering a lot of useful tips regarding options. Don't know if he is still a dealer.
During and after my purchase I also interacted with numerous people at the ATC factory. All were very helpful and quick to respond. Couldn't be happier.
