I just wanted to ad something to my second AC install. The second AC only had four screws holding the shroud on. My other AC had about twice that. I orderd more screws from dometic. When I was up on the roof of the TH I noticed that a bolt head on the bottom of the AC chassis was touching the roof. This did not look quite right. When I torque the AC down per instructions 40 to 50 inch pounds I did not think that it was over torque.

The gasket that came with the (used) second AC look ok so I did not replace it. But it had to be the gasket material, so I orderd a new one. I replaced the gasket and stabilizing blocks. Now the screw heads are well above the roof (torque to 45 in lbs)

Here are the two gasket materials, new on left old on right. You can see how compessed the old gasket had become.

My advise, just replace the gasket in the first place.
