First Time Winterizing - Did I Miss Anything?

Apparently it wasn't thorough enough. Somehow I had it in my head that the fresh water tank drained out of the low point drain. I went to the storage spot and turned on the water pump. Water was coming out of the low point drain as well as a trickle from the tub faucet. Found the fresh water tank drain and drained it, but now I have water back in the lines. Guess I have to either get a big inverter to be able to blow out the lines at the storage spot or hook the thing up, bring it here, take it back and park it. Wouldn't be so bad if I didn't need my wife to help park and if I didn't have to work till 9 tomorrow...
