Getting cold so we are putting the unit to bed. This is how I winterize, pump in a container, and push the antifreeze thru the coach and the hook to pump and let it do its thing. Takes about 10 minutes and nothing including the black flush has water in it.
So am I. My wife transfered and I quit my job and got a job at a RV Park as a Maintenance Man. The pay is a lot less but we are enjoying ourselves and live 20 minutes from that beach.
