Greetings, gang!
All legalities aside, there are some ways to deal with some logistics without moving your rig while you are workamping. If you really, really want to stay someplace, there ARE options.
If you are towing with a rig that will do so, or tow a vehichle that can, carry a container (even up to 50 gallon plastic barrels like I can in the pickup truck) for fresh water and one for waste water. You may be able to use a large propane tank on site, about 120 gallons, if you can have someone deliver. Or haul a 40 gallon tank in your pickup truck. Most states will not allow you to haul anything larger than a 7 gallon propane tank in an enclosed vehicle. The "extend-a-stay" is good for motorhomes, since they have a permanently mounted tank.
Otherwise, haul all in the back of your tow/towed vehicle. Some places sell a water bladder so you don't need a barrel for water. You can use a water transfer pump set up with a regular 12v water pump to bring water in and a 12v macerator pump to take the waste out to an appropriate place if you do not have one on site. (These macerator pumps will pump waste through a garden hose about 300 ft and you can get 'em for $160) Or haul waste out in a "blue boy." "Blue boys" are horrendously expensive vs plastic barrels, though.
I have workamped/hosted where all I got was my site and had to haul in/out. My solar panels, batteries and small generator provided plenty of power for running vacuum, power tools, big DirectTV, and satellite internet on a PC. I was not "roughing it." <bg>
