See if this concept might help you mount your TV.
Mounting to the walls with anything of much weight is an issue as the 1/8" thick walls will not take any load.
I over came this issue when I added my coat hooks. In my T2499 I did not have a convenient spot or way to add a good strong coat hook that can hang the heaviest of winter coats for DW and I.
So I took a piece of 3/4" pine board, spanned between to studs, screwed to the studs then mounted the heavy coat hooks where I needed them.
I finished the pine with clear polyurethane that deepened the color enough to closely match the Sunline Maple.
You may be able to adopt this concept any where in the camper then fasten on your TV support bracket.
See pics below as reference.
Now just the hooks and backer board.
And While I have you, the hooks pivot and have 3 hooks each on the pivot. The hooks came from Lowes.
Hope this helps.
