TV Wall Mount

Size of the screws is not the question, but rather, what is in the wall where you expect to mount it. RV wall are usually very thin material with few or no wall studs inside. If it is nothing but thin fiberboard, forget about it. Your RV may have special reinforcement especially for a TV mount, if so, go for it.

Where I'm mounting it, it says mount wall bracket here. I presume there is some sort of studding there.

I spanned three studs with a piece of 5/8" plywood. Plywood glued onto wall and two fasteners in each stud. The fasteners (bolts) for the TV mount were led from the back of the board towards the front. I captured the mount with a nut on each bolt. This supports a 32" screen.

If it is marked, then you are probably good to go. I would use the largest screws that fit the holes in the mount, and as long as you can use without coming through the other side of the wall. Probably about a #10 screw ...

If I could not determine what kind of backing those walls have showing one of those 'MOUNT HERE' stickers i would add a 1-inch back board to mount the TV Mount too...

You certainly don't want a large TV set pulling the screws through the thin walls...

Something like these wall mount photos...





You might able to tell where the added board to the back of the wall exists by just tapping on the wall... It will sound solid all the way across it if a board is behind it...

I tossed the cheap lags that came with my mount and went with grade 5 bolts and nylock style nuts on the back. Grade 5 are the decent bolts at your local big box store, not the cheap stuff and not the grade 8 expensive stuff. The bolts were just long enough to engage the nylon portion of the lock nut.

We did this in our old bunk house for the kids.
I bought a nice mount off of amazon and we already had a stud finder even tho they had the area marked out we double checked it.

Drilled our starter holes and then used the lag bolts to open them up to what we needed.
Once that was done we used the metal grinder and cut the bolts off at the appropriate length and reinstalled.
Works great!
