I have an ADCO. It seems well made. Just as side note, if you use a cover, make sure you cover the roof drains VERY WELL. I bought 4 tennis balls and intended to place one over each one. However, my wife gave two of them to the grandkids and I didn't know that until putting the cover on. I used towels and duct tape but I already have one ripped. Northern IN winters can be very windy and it didn't take long for the corner to tear. I also have a 27 DSRL and we love it! We've only camped one season in it but we look forward to a great 2015. When putting the cover on, I recommend front to back, not back to front like their video.
