You know, the one thing I miss in the forum is the ability to "like" the replies. So instead, I'll say a big thank you to all the replies. I just read through them and will be doing so again, probably more than once.
To answer the questions - I am in the research phase right now. We don't even have a TT, just really want to get there (yesterday, as far as I'm concerned but in a couple of years time as far as DH is concerned ;) ). I do have a plan of what our trip will look like and I know we'll be visiting friends (and making new ones!) across the US. I realize it's not ok to park your RV in just any neighborhood or street but as far as I can tell, it's certainly ok in some places. So I suspect we'll be doing that sometimes when visiting friends. Just made me think about the incline option when you're not in an established campground with leveled sites.
This is immensely helpful - again, thank you!
