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
