Was trying to get by without winterizing since we are in the dfw area and have plans for a trip in early Feb and march...
so far have only had 1 light freeze that I ran the furnace thru
but supposed to get in the low 20's a couple of days this week, so thought it best to do something
got this little gadget Blow Out Hose - Intersource Enterprises D16-252 - Winterizing - Camping World
and hooked up the compressor @ 35 psi and the hardest part of the job was laying down on the ground to open the low point drains in the front and in the back.
(nice that our 5er has 3 drains - hot and cold in front below our demand hot water heater and a large one behind the wheels basically under the kitchen)
really surprised how much water came out with the air pressure even after draining until no drips !
