The Coleman Mach was installed in 2000 by Metro RV in Burbank, CA. I did find what seems to be a drain hose near the left side of the trailer in front of the wheel well. No moisture was coming out of this at all. The water seeping out, however, was coming out of the right side, and there are water stains in the bedroom ceder closet. It was seeping out of a good 8' of the side of the trailer right above the decal-stripe. The trailer does not leak at all in even the hardest of rains. This all started when I ran the air for the first time.
