I have decided to go ahead and temporaryly winterize before our first real trip in Jan. to the south. Just want to double check my procedures. There are two low water points on the door side of my big horn 3055 - cold and hot water lines I think - drain those. On the off door side there is another low water drain - Main water tank I think - drain that. Are there any other drains that need to be drained? Hot water heater - (is there another place to drain it other than on the back of the unit itself?) Turn bypass lever to bypass position in the control area and the winterize lever to winterize position and pump some antifreeze through the lines. Put some antifreeze in each of the traps - bath sink, shower, and kitchen sink as well as in the toilet with enough to have some in each of the holding tanks. Does that seem to be it? Thanks for any additional suggestions.
