Hi Mark: Been out of service for a while, just came across your post, so will offer my thoughts on winterizing your coach.
I lived in Providence for a while, so I know RI, and the winters you may have.
1. You are far more money ahead to have your dealer winterize your coach if you have no experience in this area. Know that not only do you winterize your water lines, hot and cold, but your waste water lines, and your water heater.
2. Then, you winterize your batteries.
3. Then, you winterize your engine, fuel lines, windshield washer fluid and lines.
4. You probably should also remove your water filter(s).
5. I also recommend you add a dryer to your air system, then drain the air tank. Any water in the air system, and there will be water in that system in RI's humid air, will wreck your air compressor, pump, lines, or storage tank.
6. Last, you need to add a stabilizer to your fuel if you are not going to drive/start the engine for several months.
7. Did I mention winterizing the generator?
So, sometimes paying $200 to winterize your coach is more than worth the cost, to prevent your spending more than that to fix it in the spring.
