Yes, most are like just what you found. Very stark. No need to have showers or biffys if you got his and hers in the trailer. And, yes, sometimes the only way you know someone is in them is if there is a car sitting next to it or a yipping dog inside. Don't forget the satellite dish. The campground that we have been co-habitating in since May even has seasonal campers. It is much like a trailer park. Plants, signs with their names, yard art, you name it.
Our landlandy in Montana sold
RV's. She gave us the tour saving the best for the last. The remote controled fireplace. My husband has lived in smaller apartments then some. I have to say, upgrading to a toilet is nice. Good thing my husband doesn't like small spaces otherwise he'd be in there longer. We also went from a 13' to a 19' because we knew we would be living in it. When my husband first started working in Montana he thought he would just pull our 13' out and live in it. Well, in eastern Montana RV campgrounds where we were at were a gravel lot with electric hookup, no trees and full of 5th wheels with roustabouts living in them all year long. By time the 5th wheel was ready to pick up we were back in Iowa headed for Wisconsin with it.
