Haven't done it myself, but many people have. If you have the finances, go for it. Like ford truck guy said... find a way for a septic type system (or composting toilet) and a way to get power and water. Generator might get expensive and logistically difficult to run continuously. A solar setup or wind turbine system with a battery bank could give you reasonable power. Heck, get a mountain property with a stream running through it and set up a watermill to create a couple of kilowatts of power.
If I was doing it and making it semi-permanent I might set up a Carolina Carport type system for an additional roof system. That would keep water and branches off the roof, while also keeping you out of the sun and keeping additional solar gain off your roof and out of your interior space. Your camper will last a LOT longer and provide you with a covered exterior space as well.
Heck, years ago my dad talked about wanting to buy a piece of property in West Virginia that had mineral rights and drilling a natural gas well to provide free power.
