Was thinking about hanging our tv in the bedroom on a wall mount. The lag screws to hold the mount are long enough to hang my hat on the excess on the outside. What size screws are big enough to hold ...
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.
