No, but have not had it out for over a month to check it.
will be trying some anti-odor stuff to see if that helps and going to flush it real well before we go
Got a newslettere from RV Doc, and on one of the ads was a product that replaced the p trap with a straight pipe that had a one way valve that was a bladder to eliminate the odor from backing up. sorry cannot recall the name
I think it is due to the vent that is on the side and not on top.
