Make sure you know where your circuit breakers are and that you have spare fuses. Also you need a white hose (drinking water quality)for attaching to the campground faucet, its a pain to travel with a full tank of water, it keeps sloshing back and forth.
Actually with my back, I have a better time of it sleeping on the couch because it is firmer. Our is manually extended so that's a little hard for me to do but my DH does it for me before we go to bed so its ready when I get up with a sore back at 3am!.
We use our WiFi for emails and the computers/Ipads/phones, its a Verizon and seems to work pretty well up and down the east coast. A lot of campgrounds provide it but you need to be pretty close to the office to get it. I just make sure its locked with a password.
Oh meant to tell you, try to get a map of the campground beforehand so as to avoid sites near the dumpsters, I've found that no matter how much they are sprayed they always give off an odor. And if you don't like light at night, make sure you have light blocking shades. If you are sited near the showers/toilets, the lights are usually on all night and people come and go at all hours. Better to go in a well lit station than in the dark woods for some of us, especially the tent campers.
Let us know what campgrounds you stayed at on the trip, I would find them very helpful!
In the past we have stayed at the Yogi Bear campground in Natural Bridge that was a good one and also at Cherrystone in Cape Charles VA right at the water, I just loved it. They were just starting out in clam farming when we were there.
In DC years ago we stayed many times at the Cherry Hill Park in College Hill Maryland when we visited DC. Not very picturesque but close to the metro.
On our trips to Florida we always tried to stay at Army Corps of engineers sites, they were usually well maintained. Haven't done so in a few years so not sure if they still are good to stay at.
