You should be able to find a much newer Class C in better condition for 12K. We bought an old rig for 13K as beginners and wound up spending another 10K the first year on engine cooling system, AC, water heater, etc., etc, just to make it safe to drive and usable for camping/touring. Read advice on buying a used Class C on this forum and don't rush to buy. Consider paying a truck mechanic and an RV repair place to inspect and provide an itemized price list for needed repairs and replacements on a prospective buy.
