There is an RV section on CL that you can advertise it in. Anyone with an RV that is looking for something will look there. Maybe others here never would and wouldn't pay, but some people do buy older units and fix them up. I would start the dinnette seats/table at $100 obo and the love seat the same unless it's some wild print that no one will want. If it's somthing neutral or subtle that many people would be able to use, then that would be my starting point. You can always pull it off and wait a couple weeks to re-advertise at a different price. Spring may be a better time though.
