I am very proud of myself.
Today I installed the RV Pump Converter Winterizing Kit in our 2007, T2753. It was quite a job hooking up the fresh water hose to the brass valve. Sunline did not leave extra length of tubing to attach to the valve. It is installed however and the trailer is winterized, now saving me $40, less the cost of 2 gallons of antifreeze, each year. For those who have never home winterized your RV, it is much easier than I imagined. The hard part was making the decision and doing it.
Now, as in the past, it's going to be tough watching our trailer sit and sleep behind our house, waiting for Winter to pass through, and Spring to come again.
