Since I got my surge protector I always plug in first. This allows me to see if there are an issues with the electric. Never know you may have to relocate to another site if the power is bad. After that it's jacks down, then water and lastly sewer. Over time you will develop you own routine and set up. I've been camping for 15 years, I still find myself evolving with regard to set up. The wife and kids pitch in and help now. Remember if your hooked up to sewer you can leave the grey water valve open. Black water valve is always closed and dumped as needed. This allows the water to flush solids away. Walk the campground and see how others set up. Get there early if you can and set up before the rush. The most important advice is get where you going before dark, at least until you have your routine down. Go slow and take your time.
