Sqeaking Floors

We bought our BH last June and have really enjoyed our new rigNone.
We are now wintering in Arizona and have developed this sqeak in the kitchen that seems to be along the heating duct from the cupboerds to the bdrm steps.
Has anyone else had this a problem and idea for a fix?

We had a squeak in the kitchen of our 3400. A Heartland dealer attempted to fix it by opening up the underbell and shimming the floor. This eliminated the squeak but it only lasted a couple months. I did my own fix by cutting through the vinyl flooring and rolling back the vinyl to expose the sheathing. I Found the studs and used drywall screws to secure the sheathing. I did the whole kitchen area so as to prevent future squeaks. I recently replaced the vinyl flooring with laminate tile flooring. So far, no new squeaks.

Holy Smokes, Ray. You might want to go into business with custom floor works! Nice work.

Ray, I also agree. I couldn't even tell where the laminate comes together based upon the pattern. Great job.
