Another scammer posting fake RV/camper ads on craigslist.  They have no real RVs, campers or motorhomes to sell; they will direct you to a fake eBay, Paypal or Amazon page, or ask you to send money via prepaid card or iTunes to a fake "shipper."  They may even give you a story about being on an oil rig or being overseas in the military, or the original owner died.

Never pay for a vehicle you can't inspect in person.
