Personally I have a different take on using these outlets when traveling to get to a place that I intend on staying for a bit. I just want to be able to pull in and kick back for a while before going to bed while not paying the prices and throwing away some extra money in our view for normal developed campgrounds. Of course I am set up for being somewhat self contained and I don't need the normal services. This is important.
But we camped a lot of years with the simple things in a self contained and enclosed camper and never thought about demanding cable tv, 50 amp services and dump provision at the campsite. We have never used tons of water when knowing that the access can be limited. Everyone is different. I personally camped across the country and worked briefly out of a VW van and had a blast enjoying the outdoors. Our ac consisted of rolling down the front windows and running 50 mph max, unless going downhill, when the winds were not blowing really hard.
So its always been a habit to conserve. Living most of our lives on wells, we also understand planning ahead to have at least a few days of extra water for the essentials, which has been standard practice. So what, I donate a bit for a decent parking lot in mostly quiet areas.
Harvest Hosts has also been a great mix for us, even though there seems to be more pressure to buy a product at their wine outlets than most of the farms. But the farms have been a good outlet for stuff we would buy anyway when on the road, eggs, some meat and even gifts like alpaca byproducts. So as long as I am able to travel, I will seek out the different avenues avaliable from the KOAs and the likes. I don't mind the out of the way family and independent campgrounds to replenish on the back roads.
