Gary, I bet that rattling above the cab is either excess cable/tv wire, or in the case of mine, all of the above and the wire from the backup camera, which resulted in certain wires that WERE glued to the headliner to be flopping free. My tv also caused part of the problem, tho' that was more of a screech/creak, and one more thing: the cab roof itself, fluttering against the wood shelf above. A few well placed drywall screws, silicone sealer and spray foam took care of most of the problem.
Trouble is, mine is still full of rattles all over the coach, which is very disappointing since I hate rattles, and Dario has none in his 225.
Right now my 213 is at the dealer again for most of the warranty work that was NOT done the first time, as well as new problems, like a tank heater that is 'ungluing' from the black tank.
Wonder if the Four Winds vehicles have these problems?
