Mo LaRocque

I have a black water holding tank and put zero paper in the toilet and use a ceramic boat tankless toilet. Difference in emptying costs for one person, 1750 gallon tank is almost 2 years vs 2 months. Emptying costs vary but are around 350$ Cdn.  Otherwise 12 months at 350$ per shot 4500$ /2years vs 700$/2years.
Not bad.
