2004 Keystone Outback feedback

If this model has the filon (non fiberglass) front cap, I would look very closely for signs of delamination of the cap due to leaks at front roof seam or marker lights. Of course you should look for any signs of water intrusion evrywhere. If it has been well maintained, probably a decent rig. If tires are over 4 years old, plan on replacing them and having bearings repacked and brakes checked/replaced as needed.
