If it's a typical old rig and has not been kept repaired and maintained and updated well, and you are not skilled in truck mechanics, RV body work, electrical, plumbing and gas operated appliance repair, you could spend over $10K on the rig the first year getting it ready and reliable for full enjoyable use with everything working properly. My advice, save your money and buy a 3-5 year old rig with everything working and new safe tires, if you and yours really want to enjoy RV-ing. Speaking from personal experience. Owning ad RV is a hobby in itself, like owning a cabin cruiser or an airplane.
