Im out here in Rapid City. If you need some help, try to look around the local facebook groups, or just use craigslist. Currently though, good luck finding a 240 up here, that is for sale. You might try a bit further out, like Denver or such. Are you located on the East or West side of the state?
EDIT: Here is an example of what I mean...Denver CL has two for sale, and a Skyline.
