I dont have an RV also I sleep in the back of my pickup with a good sleeping bag.
You have time to plan , I have always liked the tent in the bed of the truck . Last time I stayed in the back of my truck it was a full moon and it felt like some one had a flash lite in my face all night . Also if your near one of the trailer you can run a cord and a elc. blanket , even if it's not on all night it will be nice and warm when you go to bed .
