Those are nice coaches, my first coach was a used Damon Daybreak and we loved it. Take your time and spend at least an hour looking at each coach and take a long test drive. When my wife and I were looking for a new used coach i would have her walk behind me with a pen and paper just listing all the negative things about each coach, you can use it to negotiate. The coaches you are looking at may need some service so you can have that negotiated in the sale with the dealer. At the very least i would have the dealer install 6 new tires (no matter what condition the current are), 2 new coach batteries ,1 chassis battery, re-coat rubber roof, service engine, service generator and repair any deficiencies. That maintenance will give you piece of mind and a good starting point. Good luck , remember shopping for them is half the fun take your time!
