We just got our skoolie and used
https://harvesthosts.com/ immediately. You must be able to boondock (although a few hosts have electric hookups), must call ahead (most just the same day is ok), and are expected to spend $20 at the business. We stayed at a brewery/winery (and spent much more than $20!), and then two farms - there was nothing to buy on either if them as it was waaay off season for farm goods; we handed one guy a bit of cash and the other didn’t want anything. It is only for one night unless you’re specifically invited for longer. Skoolies are explicitly included in the types of vehicles. Please, please use courtesy - we loved our stays and want the service to continue!
