Good advise for couch owners.

It took a number of years to chase down the noises in our PC. Apparently I "did good" because the remedies (and practices) continue to work. They don't return, they stay gone. It was well my effort. Life on the road in our PC is a pleasure.
sources of rattles creaks and bangs for us with no slide out were.....
- microwave oven (replaced wood screws with spiked "T" nuts and regular screws)
- overhead TV (opened it up and added felt pads throughout the metal shielding inside)
- crank-up roof antenna (added felt pads under the feet and wings)
- flip-up counter (added felt pads in the hinge areas)
- stove grates (placed silicone pot holders on them, then set the Corian covers)
- entry door (Replace frame mounting screws with stronger, spray WD40, and adjustment the "catch")
- B+ cap (screwed the wood base cabinets to the steel roof underneath)
- the contents we bring along (padded drawer & cabinet liners & half-sheets of paper towels between items)
