Welcome to the forums and congrats on your Sunseeker! If you don't mind sharing where will you be heading for your maiden voyage?
My suggestion would be to keep things simple while you determine your camping style. Many of us brought anything and everything only to find out later on that we don't really need it. Another tip would be to remember that campsite neighbors are a great resource. RVers are a friendly group eager to help another RVer out especially if they are new owners.
Great choice for "Living within my means" and camping for one...
