My trailer is rated 20 gallons, but they count the 5 gallon hot water heater, so I have a 15 gallon fresh tank. I have 50 gallons of waste storage (30 gray, 20 black).
Dutchmen: I like the looks of that TSC "leg tank"... I'll stop by TSC and have a gander maybe this weekend. Too cold for hauling extra water right now, but I can dream of spring :)
mbopp: Where did you score those barrels, the price is certainly right?! They look like they're from the food service industry? Once in a blue moon our local surplus warehouse has blue 50 gallon food service barrels from a company that makes pickles. I don't know if I'd ever be able to get the pickle smell out of the plastic - it's very strong when you open the barrel even though they claim to have pressure washed them.
