"water leak...found it in tubing that is behind a drawer that is under my stovetop."
While I'm not familiar with the Flair, I've found that stovetops in most coaches can be easily removed. That is how we repaired ours (actually, replaced) the water tubing from the sink to the fridge ice maker.
In our coach that tubing should be fastened to the wall above the furnace; it slipped down to make contact and a small hole burned through. If your layout is similar, when it is repaired, make sure everything is properly suspended so no furnace contact can be made.
Fleetwood is not known for sending mobile techs out unless there is an emergency. Plead your case with something the damsel in distress scenario; you might get better results!
BTW, when you call be sure to have your FIN# handy (not VIN). On our coach it is on a tag outside beneath the driver's mirror. Many people say it is also posted on the wall behind their pilot seats, but on mine it is not--only the VIN is there (other numbers to, for the engine, transmission, axles).
