Thank you so much for the wonderful detailed replies everyone! Much appreciated! I have a steep learning curve ahead of me and we won't have a lot of time to learn once we start since we'll be coming from overseas.
I realize some things we'll just have to figure out for ourselves (and that's part of the fun!) but I am trying to learn as much as I can before we come and insights from experienced RV'ers are invaluable for me!
(Don't worry, I still have a few years of learning time ahead of me :( - we're waiting for our sons to finish their military duties here first).
