How large is the waste on a 2002 viper. Sometimes mine seems to fill up so the don't flush light comes on at night and its just the wife using it to pee in the toilet.

I went through all my old PQ brochures and magazine articles but could find a spec. The fresh water tank is 25 gal.

How much beer does the wife drink anyway to fill the waste tank? LOL!

Waste I think is 5 gallon....fresh water is either 12 or 15

Not meaning to be an ass but all my old PQ brochures list (where listed) the fresh water tank capacity for Avengers at 26 gallon. Interestingly the same brochures don't list the Vyper's spec. Still no luck finding the waste tank capacity.

No worries here, all good.

I have The brochures but too lazy to look them up. In the next days I will. I am pretty sure the numbers I stated above are correct.
