Welcome and congrats on your new coach. Yes, a new coach can be a little overwhelming at first, but just take one thing at a time and you will get used to it in short order. You may want to get a copy of Ed's manual as there is a lot of good info in it that will help now and down the road.

As far as campgrounds, you may want to check with
RV Park Reviews - Trusted Reviews of Campgrounds & RV Parks for campgrounds that are suitable for your style of camping if you are new to camping. If you want to do it on a budget like we do, you may want to consider joining one of the discount campground org's. We belong to Passport America which is half price off on their participating campgrounds. There are some restrictions though, but you usually get back your annual fee in two or three nights of half price camping.
Happy trails
