Thank you all for such great replies!

The big attraction of full time RVing would be to get out of the Pittsburgh area and see our country. I would try to stay out of the freezing temperatures as much as possible but want to be prepared and have a game plan if I'm stuck in freezing temperatures and would have to leave the trailer.
The bear, pconroy darsben and coolmom your suggestions definitely made it into my notebook of research. Sounds like a quick winterization would be the best bet. I've watched a few "how-to" videos on YouTube and seems very doable as part of a going to work checklist.
Stew - good point. I would only come back this way during the nicer seasons. I can see where some advanced planning would be beneficial in some areas.
Pghbob,I definitely want to hear about obstacles I might face! I do love Pittsburgh but the goal is to get west. Montana in the summer and south California in the winter sounds too good to pass up.
Old-biscuit - I think I would end up leaving the RV on camp grounds without hook ups. I also read that people will let RVs stay on their land for a small fee without hook ups. Dumping water could be an issue but I also read they have portable tanks you can transfer your waste water into...then take it to a dump station. I would be able to commute to work for nearly any airport with airline service.
I appreciate everyone taking time to post..thank you. Cheers!
