For an Class A motorhome (or B or C) "setting up camp" can be as simple as stopping in a level place, shutting off the engine and setting the parking brake. Slideouts complicate matters only slightly.
Power, water, sewer hookups, site decorations, awnings, additional shelters, patio gear, are all optional. After all, it is a self-contained home on wheels, there is no need for any camping unless you want to add camping to the experience.
The harder part of getting started RVing was figuring out just what it was we wanted to do (camp, travel, have a seasonal home or vacation home) and until we figured that out, we couldn't figure out what kind of RV would fit that purpose, so we were more than a year looking at three classes of motorhome and two classes of towable (wife ruled out tent trailers and truck campers) in a lot of different sizes.
Biggest mistake I see newbies make, and they don't make it too many times, is to separate their trailer from their tow vehicle before it is firmly chocked on the parking site. First time it rolls back off the site and over the bluff will cure you of that one.
