TV wall mount screws ?

Thanks, I might just take it back in and see if they will mount it at the dealer. Our CW is a little slow.

Here is the info you need from the engineering team that designed your model. Read the last couple of posts.

I would suspect that the mount the OP bought is for residential use, thus the 3" screws included. That makes sense.

I have never seen a three inch wall in a RV, but I haven't seen every wall in every RV.

Those screws might be three inches long for a reason- shelf/TV combos can be heavy! But they sound awfully long for something that's designed to go on the wall of an RV- who has walls that thick??? In an RV, I mean.

If the hardware was in fact designed for RV use, is it possible that there's some sort of intervening support that the screws also go through?

Using 1.5" screws are probably safe. Why not measure? You should be able to determine the thickness of the wall at a window, door, or baggage door.
