For those of you who think I need to get out more, I can only say that for the first two years after I retired, my wife and I and two cats full timed. The average cost of camping was $7/night. For the past 3 years I have only gone out for a few months of each year. I have camped in almost all of the 48 States. Sure there are places for big rigs that don't require $25 plus costs per night. And some big rigs can get by very well without hookups. (Not with laundry operating, however) There are also a great many places available to smaller rigs that will not accommodate a big rig.
It all comes down to what you want. I like to travel and see beautiful locations. I rarely park in one location for more than a few days, if that long. I want to be comfortable when I travel but I can give up the laundry, bathtub, sewing machine, home entertainment system, walkin closets, 30 cubic foot refrigerator, and 40" flat screen TV. With all the traveling I have done, I have never even tested to see that my small TV works. I do travel with computers, lots of photography gear, archery equipment, emergency tools, and 4 seasons of clothing to handle all but severe winter conditions.
Handling several weeks of dirty laundry is not an issue. I don't put my clothing away wet and sweaty. I store it in a laundry bag outside the camper in the wheel wells of my truck. Even at home I rarely do laundry more than every 2 or 3 weeks. Over the years, I have passed by a handful of Laundromats. Those of exceptions. Laundry facilities seem to be highly competitive and most facilities are clean and low cost. While the machines are running I usually do the heavy cleaning on the RV, including waxing the floors and cleaning all the windows.
