Need info on 1989 Tioga Montara

There are lots of opinions about buying new vs used RV's. My advice in a nutshell: Short Class C's have little cabinet and storage space and poor sleeping setup especially if you have, or will have, arthritis or agility problems. You will need at least a 26 foot rig to have a rear bedroom with RV Queen sized bed with access on one side. A bed with access on both sides is much better for getting out of bed without disturbing your partner but that requires a small bedroom slide or 28+foot rig. Take your time looking at floor plans and lengths and features offered by various brands and year/models. Don't buy on impulse. Try to buy a rig that is three or four years old and have it inspected by a pro truck mechanic and an independent RV repair service, get written estimates for any repairs, replacements or upgrades needed for full functionality. Tires need to be replaced when 4-6 years old regardless of looks and mileage. Roof and dash AC units, fresh water pumps, and house and starting batteries can last for ten years. Expect to spend some serious money with any RV in addition to purchase price, DMV fees, taxes, insurance and periodic maintenance and storage lot costs if needed. Don't buy an extended warranty, most are full of maintenance requirements and loopholes. Set aside money in a bank account for repairs and other costs. RV ownership is not cheap, Owning and maintaining an RV is similar to owning and maintaining a cabin cruiser boat or an airplane.
