Do what the rest of us have to do and that is find an RV storage place. I wouldn't leave it in Puyallup unless it was under covered storage. Preferably take it someplace dryer and then find a covered storage spot.
Our DP hasn't been home since I retired 6 years ago. We usually leave it in AZ, but it's been stored all over the US when we fly home for a couple of months at a time.
