Squeaky cab overhead

[KJulsen]

We have a 2012 Winnebago Access 26 foot class C on a Ford F53 chassis. I bought in new in Colorado and drove it to Alaska. There was a slight squeaky noise in the cab over the passenger seat when driving. Having owned a Monaco Class C motorhome for 30 plus yeas I thought a few small noises were ok. Now the squeak seems to have gotten worse or maybe my tolerance is less. The noise appears to be coming from the area were the overhead structure meets the cutout in the cab.
I looked on this site and found a few posts that suggest loose attachments were found on other motorhomes. This last fall I removed some of the upper bed area to expose part of the area and it seems that those screw are all tight. I also did some work on areas that could have been rubbing together making a squeak. Not wanting to damage anything I put everything back together. This did not cure the main squeak.
It sounds to me like the gasket between the overhead structure and the metal cab is the culprit but unsure how difficult it is to get to.
The noise is worse on rough roads. I live in Alaska and most roads are considered rough depending on the time of year.
Has this been a problem for others?
Has anyone removed the overhead cab bed to access this area and what were the difficulties?
Remedies?
Thanks

That is not an F53 chassis. That is the bare chassis used on the Class A motorhomes. You have either a E-350 or E-450 chassis.

The bed in my View came out easy, just lift it up, disconnect the struts and slip it up and aft out of the hinges. I think they all squeek some.

Having all winter to build up the courage I decided this spring to remove the headliner in the cab of our 2012 Winnebago Access 26 foot class C camper on a Ford E 450 (miss identified in my original post). The job was not hard. The sun visors needed to be removed and the fabric retaining screws removed. There were 2 screws under the fabric holding the thin plywood stiffener to the cab metal that I just broke the wood.
With the fabric removed the Ford cab metal was exposed where is attached to the wood structure of the camper. The first thing I noticed was the dark spot by the screw heads showing where the metal was fretted away over the passenger side. This is where the noise was coming from. Checking the screws, they were found to be minutely lose where there were dark spots. I tighten all screws and used a little Navy knowledge that if a little bit is good a lot is better adding 100% more screws. Reassembly was a little tough aligning the screw holes, but patience paid off.
A test drive proved the noise was now gone.
3 picture are attached, hope they show properly.
Thanks for the support. I enjoy reading the post and the responses.

I am glad you found the solution.....I like that!

Our B+ rig developed a squeak in the cabinets above. I realize it's a different rig and a different configuration, but some of what I did may provide the solution for others reading this.
