Hi Zolman!
Based on my limited (but recent) experience, I don't think you'll have any problems.
I picked up my new 2552 in Elkhart on February 12. I had them put about 3/4 tank of water in the tank, and spent the first night at the Phoenix lot, and the second night at the fairgrounds near Elkhart. Both nights we received substantial ice and snow, with a tough wind and temperatures dipping below 20 degrees. After two days of familiarization and evaluation, I picked up my Jeep tow conversion at Dan's in Elkhart, and started back to Oklahoma the afternoon of the 14th. I ran down through Indianapolis and over to St. Louis, but because of continuing snow, poor road conditions, and (slowww) congested truck traffic, it took all of both days to make it through Indiana and Missouri. I ended up overnight at Cracker Barrels by Terre Haute and St. Louis the nights of the 14th and 15th--again with both nights in the mid 20's. I ran the tank heaters on the black and grey tanks and the LP on the water heater, and with the Ford cab heater during the day and furnace at night, the interior never got below 60. I used all the coach systems over the four-day period with no problems. As soon as I got back to Oklahoma, I drained, dumped, and winterized--since we've still got some winter left here (temps in the single digits tomorrow). I think you could either leave your water heater bypassed, or if you want hot water, you could open it up and keep it running with LP or electric just fine.
I can't recommend taking delivery of an RV in northern Indiana in February as ideal, but I have to say that the rig performed without a glitch over the four days in pretty difficult conditions. I don't plan a lot of winter travel in the future, but this experience convinced me that the PC can do it if necessary.
All the best, Mike
