We have a 2008 Bighorn 3670RL. We are getting a bad musty smell under and in our fifth wheel. It seems to originate under the stair area, but premates the whole trailer. There is no odor in the dirty clothes hatch in the hall. We have holding tank treatment in all drains in kitchen, bathroom and toilet. Any ideas on what we should check on? We are first year snowbirds and hate being the smelly ones in the park. None

Thanks, Linda

Just a thought on your problem, we have a 2006 bighorn and it had a dripping leak at the connections going to the shower. There is a 7 inch plate on the rear of the shower just above the control valves, that screws on or, at least does on ours, that can be removed to check for the water connections on the shower. If it has a drip, that would be a source of your problems. Good luck.

I don't know if the units are the same. Ours is a 3400. I found a leak in the pot, just a small bit with each use. Water was dripping into the floor area behind the main switches. Took a while but was smelling bad. Fixed the leak and stopped the smell.
good luck

Thanks guys, We had been having trouble with a small leak from the toilet, but thought we were keeping it wiped up. Husband crawled under trailer with a flashlight and found wet wood. We have a pan under the leaking valve now and hope the dry Arizona air will dry it out soon. The smell has improved. We've called and scheduled an appointment with the service department when we return home next month.

One of the Bighorn owners in the park we are staying at had the same problem and three trips to the dealer did not solve the problem. He finally called Dometic who sent him a new valve. The old valve had a brass cap on top of the plastic valve assembly and it was slightly cross-threaded. The new one from Dometic was all plastic. This has now solved his problem. Maybe you will see the same for your unit. His was a 2008 3055.
