i am new to the Forum, Rving and to our 2012 29SS Sunset Trail Reserve. we love this trailer however i found a few issues, and wanted some other takes on it. I found we have a pretty foul odor coming from the cabinets under the kitchen sink. It looks like after some investigation like their is a vent located inside the cabinet. Reminds me like the ones used in a home where you dont have roof access. Problem is the stink. any help would be greatly appreciated as our trailer is in a permanent site.
