I don't know if you need to worry about freezing in New Mexico, but just in case, here is how I winterize my 22M using the blow-out method
. My neighbor runs the pink stuff through his fresh water lines, and he says it takes a long time to get rid of the taste. I certainly like very clean water, so I only use antifreeze in the traps and to wet the the bottoms of the black & grey tanks.
Is it true that it really isn't new, and it really isn't Mexico?
I must get new jokes.
