Need help finding a TC with a slide out - on a tight budget

finding a half decent truck camper with a slide for 5 grand is going to be tough. But with enough effort and perseverance it can be possibly done. I would put wanted ads in the local papers and see what shows up. sometimes wanted ads will be found by a seller who would rather just get rid of something that he is not using, but doesn't want to mess around with placing ads and answering phone calls from a bunch of tire kickers.
good luck, Joel
