Quit my job, Traveling for 1 year

If I were you, I would buy a used Class C from a rental company. While high mileage, you will get complete service records and a solid coach and chassis. While I appreciate your desire to travel, your scheme is wrought with many potential derailments. The biggest is buying a RV that has issues hidden to the lay person's eye. Water intrusion is the biggest issue, and the second is poor design causing severe road handling issues. Don't count on any dealer helping you with anything except parting with your money. Also, you need to be very handy diagnosing and fixing things or very handy with your check book.
