Good luck screening daily and weekly renters. What are you planning on doing, running background checks on everyone who wants to rent a place for three days? Or are you going with the "cross your heart and hope to die" pledge that what they are telling you is true?
Good luck finding that subset of daily and weekly renters that want (and can actually properly maintain and use) rental properties that are off the grid. Your average renter will have no experience or appreciation for a composting toilet, a generator or solar for power and having limited water.
Good luck finding someone who just wants a place in the middle of a field. When most people think of boondocking, they think of great places that are otherwise inaccessible. Not the middle of a corn field. Great boondocking locations have more going for them than just isolation. Like another poster implied, total isolation for the sake of isolation mainly appeals to meth cookers, escaped convicts, pedophiles and the Unabomber, none of whom are a great demographic to target for a lodging business.
