We have a '95 Bounder, our fresh water tank has a drain on the hose from the bottom of the tank that leads to the water pump (this tank is located on the passenger side, forward of the rear axle). The water pump is located on the drivers side. The water heater also has a drain.
we just drain everything, go the Walmart, or Target,(insert favorite chain store name) purchase 10 gallons RV anti-freeze, pour 5-6 gallons into fresh water tank(after you re-close all drains) turn on water pump, run solution thru all faucets, and toilet, shower. then dump a gallon in the toilet and flush, dump 1/2 gall in all sink and shower drains.
