Newbie TrailManor Owners

Hello Everyone,
After lurking about on the Forum pages for a few weeks, we took the plunge and bought a 2007 2720SL which the former owners purchased new in April of '08. Gratefully they delivered it and backed it into the garage as we had no TV as yet. Now we have an '09 Toyota Highlander with a 5,000 lb towing package, a class III hitch, a Prodigy brake controller, McKesh mirrors, more manuals than we can read (or certainly retain) and an itch to hit the open road once the Highlander has 2,000 miles on it.
We have successfully set up and taken down a couple of times but have yet to try any of the hookups, appliances, etc, so a big learning curve remains. Eons ago, we had a little tent trailer that I could literally pull by hand from one campsite to another, so this is a new ballgame.
Thanks to all the veterans for such helpful advice.
