Never heard of a warranty like this

RV paper disintegrates easily with contact with water. Regular paper often bunches up in wads which can clog RV tanks, plumbing and valves. I've not seen that stated as part of a warranty but makes sense.

I take you haven't seen the various TP disintegration tests that have been done numerous times. The common off the shelf septic tank safe TP brands typically perform as well or better than the more costly "RV TP" brands. We've used Charmin Ultra Soft in our RV's for years with no problems. It may not break down quite as quick as some of the single ply TP brands, but it's still plenty fast enough for everyday use with no clogging. The key to keeping RV waste tanks from clogging, regardless of the paper used, is using sufficient flush water.
