Plan to try the happy camper extreme unless someone has a better idea.
Happy Camper Extreme is a good start followed by Happy Camper on a regular basis. It is also a good idea to charge your tanks after dumping (add about two gal of water to both tanks with som HC for the ride home. That continuous sloshing will work wonders for the tanks and sensors as you drive.
