Planning to use a porta-potti in the "FOAM DUCK". But the main reason is the DW has parkinson's and myesthenia gravis. The latter makes it cquite difficult for her walk to and use the toilets at most cg's. Besides I always use the "geo method" - Twenty Mule Team borax, a little calgon. Right down into the holding tank. Put it in just before "gear-up" at home. By the time you get to cg, ready to use and NO ODOR, cleaner tank. And great for the environment. And it REALLY WORKS. Been using it in the big 26' Wildwood we are selling. Only used "rv chems" one time. Nearly barfed from the smell of formaldehyde.

GEO has no odor and keeps the tank cleaner.

Always remember: You can't fly with eagles if all you hang around with are turkeys.
