Jim depending on how many you need you might do a combination of the two and find which works better in your situation. Removing the axles of a Class A or any motor home is probably a non-starter, so you'll limit yourself there. Some may prefer a shorter stay until they get to know the situation, coming in blind and having to have axles removed may scare off some too. But after a month others may want to move on, then come back later to do a 90 day stint.
Based on the board and your experience I assume you've looked into any possible exemption for to the land use rules of the area.
With your situation you're going to need to be a bit picky about who you allow to work/stay there, youth protection policies, background checks etc. All of this could make things a challenge. You might reach out to the Oregon State parks and talk/learn from their camp host program, can reach them at the Parks Info Center at 800-551-6949 or park.info@oregon.gov
