I just had our Class A winterized and was wondering why could you not just blow out all the water lines and make sure you have "NO" water in the RV during the cold months? Yes, I am new at Rving. Gues...
I blow out the lines, but I also use AF. I mean it's pretty sumple. A few bucks for AF and hook the siphon to the water pump it takes about 5 minutes. Worth it to me. Some people never have an issue just blowing it out. For as simple and cheap as it is I am not taking any chances. That's a heck of a problem to fix come spring and could ruin the first trip.
