OP is going to be in Yuma all winter. I don't think one tank of water will last that long.
OP, there are several water softener services in Yuma, see if one will rent a unit for that time. I also have an On The Go, and it is not the way to go for AZ hard water.
I'm in Lake Havasu and ended up buying a residential water softener for my park model.
