I am trying to winterize my 2012 Rushmore and the nifty little winterizing kit will pull pink antifreeze through the cold water line but with the bypass valve for the hot water heater turned on so as not to fill the water heater full of pink stuff I cannot anything to run through the hot lines.
sounds like mine. Took me an hr to find the valve beside the pump. Its hidden in the compartment behind the storage bay, in the dark . No lights you need a flash light to see it then its in with all the water lines to. I can barley reach it. Dumb spot to have it, plus you need to empty the whole bay to get at the small door
