We picked up our W at the end of last March up here in Illinois. The motor home may have come from the factory with no water in the systems, but the dealer made everything work for the pre delivery inspection. When we drove it off the lot there was no water in the tanks, but the water lines were not cleared, and no anti freeze was used... the dealer felt that it was not necessary. The weather was pretty mild, and we took it up to Wisconsin and parked it. Two weeks later we headed out on our first trip, and when we started in was in the low 20's with about 4" of fresh snow on the ground. We filled it with water and beat feet South, and saw no more snow or freezing weather.
Seems like you should be OK in Kentucky in March, but if the cold persists, have the dealer winterize it while you are there for the PDI... you will learn a lot about your new W!
