aussiedog, Most of us go through all the systems on the rv before we take that first big trip. This is normally done at a pre delivery inspection at your dealer when you first pick up your rig. Once we get it home,at least we did, we go camping in the driveway. Use the a/c or furnace for comfort control, Use all the systems, check for leaks under the sinks and around the hot water heater, docking center and behind the wall that hides all the plumbing. Once we've camped in the driveway a night or 2 we hit the road. Usually all is well. Have a great trip.
