I've had luck selling small stuff (tractor implements, diesel generator, etc.) on Craigslist, but sold a truck on Hemmings to an out-of-state buyer. I'd never do it again and according to the buyer, neither will he.
Its a good looking truck and would command a pretty penny up north in the summer. We're battening down the hatches for winter though, so this market is slowing down.
BTW - the OBS trucks are literally only memories in the rust belt and are coming around in collectability.
