Answered the same thing over on the FR site, but if you are Thor you just use a single crappy tiny screw to put stuff up. That way blinds and such fall off going down the road.

I've used sheet metal screws installing my new over-the-range microwave. I generally drill pilot holes first, so I don't use self tapping.

I forgot to add, you really need to use wallboard bolts (molly bolts) if you don't want them to pull out.

Not sure of your design, is the wall an exterior or interior wall?

Mine was an interior wall, don't remember which screws I used. I just verified that they were shorter than the thickness of the wall. I did drill pilot holes.

WIth the wooden backing board, molly bolts would not work. Also, be careful with molly bolts, most would be too long on an RV wall thickness, and the interior walls on my TT would just rip right out I would expect. They do make short mollys, I have some in my hardware stores, but even the short ones are probably too long.

It also depends upon if you are attempting to hit the wall studs or not. And if you want to hit the wall studs, are the studs aluminum or wood?

Your best avenue is to attach a board to the wall and make sure the attached screws actually hit studs, if that be wood or aluminum.

Then, mount the television to the board. This give you extra thickness, and a firm support.

You can also give the back of the board a good squirt of Liquid Nails before attaching.

If you want, you can add a couple Moly Bolts between the studs. But the real support will be from the studs.

I would also recommend you hit the studs.

This^^^^

The only thing I'll add is that a piece of 1/2" or 3/4" plywood would be better than a plank board.

...oh yeah, my wife (

) would make make paint or stain that board too.

How do you find the aluminum stud? Do normal stud finders work?

Depends on the type of stud finder.

But there are very few vertical studs in an aluminum/foam/fiberglass camper.
Mostly just the corners and the perimeter of door & slide openings will have a stud.

If your lucky there will be a sheet metal strip laminated in between the inner paneling and the foam.
It's installed there so they can mount TVs, cabinets, etc.
See the pic below of the wall in the 5ver I just rebuilt.
