We have a rule that nobody s$&@s in the van, this way we have gone as much as two weeks without dumping our 10 gallon black water tank on our AS Interstate.
Without getting into "potty talk" I am surprised at the arbitrary use of the commode. A full service bathroom with sink, toilet and wand shower, make a Class B a fully self-contained RV. The envelopes of tank chemicals are sized and formulated for holding tanks several time larger than the 10 or 15 gal. tanks of a B, so the concentration of chemicals is much higher. When we dump, I use rubber gloves, wash out the hose and spray tilex in the storage compartment after stowing the hose. The grey water tank always governs the timing of when to dump anyway. We have never had a problem with our waste water tanks.
