How old is too old, subjective question but I want opinions

Our's is a 2002 Fleetwood. We know every inch of that coach. We know how she drives, sounds, rides and how everything works. I spoil that coach and treat her gently. When we get inside and start a trip we are relaxed knowing we are going to have a great trip. I don't worry about breaking down.

Obviously you have maintained your coach well. It's part of your family so to speak. Keep enjoying her and the memories you have with her. Once you sell the coach, it will be gone. No turning back
