We had a couple of popups over a period of 8 years and we loved every minute of it. You'll find that even with all the conveniences that popups have you still get that "camping feeling" because you can hear the birds and night sounds when you go to bed.
A couple of suggestions...
There is a website called popupgizmos.com that sells a couple of things that will make you life much better.
One is an A/C brace that stabilizes the plastic cover on your A/C so that the shroud doesn't crack. For some reason this is very common on popups. Also they sell custom made solar reflector bunk end covers that truly work wonders on helping keep the interior of your popup cool when it's very hot outside. If you contact them, tell them you heard about them from me and maybe they'll send you a free pencil or something.
You might want to checkout popupexplorer.com for lots of storage and camping help.
Good luck with the Rockwood. We had a Rockwood for 5 years that we absolutely loved. Great campers.
