Wildtoad's Family did it up right. We have a Mountain House and another Lot, and folks do the same there: upgrade the Lot to pull in and have an instant 'Home away from Home'.
I bought and set up a '31 Avion to be on site part-time while building our Retirement House in W. CO.. Since we ran Power and Septic anyway, I put in those amenities to a future RV spot and parked the Avion there to enjoy some stunning Sunsets in comfort.
Another way to go - so that the Budget doesn't get overwhelming initially - is to put up just the very basic amenities. Lay down some Gravel if a Concrete Pad is too pricy initially. Fill a small 'dry' Well ~6' deep with Gravel to dump your Grey Water safely. Move the Rig occasionally to dump your Black Water if a Septic System is too pricy at first. Start with some Solar PV Panels for power or run 50 Amp power in PVC up to a few hundred feet away. Or, run the Genny occasionally. Drop a Propane Tank. Water can be run several hundred feet using 1" or larger Black Irrigation flex Pipe and have it self-drain if req'd; an easy exercise. A surprising number of folks fill a reinforced Water Tank on a small Utility Trailer and 'bring the Mountain to Mohammed', as the old saying goes. Haul your water occasionally to your RV; not vice-versa. You get the picture...
We really enjoyed the 'change in scenery' in the Avion vs. the House, and will start Road Trippin' soon in a lil 15' used TT I just picked up that, unlike the Avion, my SUV can tow.
Once you trick out your new location the way you want it, and so it doesn't feel like some austerity program to be there, my experience is that you'll really like it. Plus, you can easily stay within Cellphone or Personal Communicator contact a short distance away from Nursing Staff.
I think the whole 'Small House' movement is pretty kewl, having been to Japan repeatedly. Small spaces can be very comfortable; even when they have wheels.
