screwing into wall with components

A trick for drilling (although the above advice is probably better) is to figure what the thickness of the wall material is (probably 1/8") and then wrap lots of layers around your drill bit leaving just the depth of the wall, so that you won't punch through far enough to do damage to the components behind the wall board. Once a small hole is through you can use a wire to feel around in the hole to know if it's really safe to do much else there.

You also have to be concerned with the THIN RV walls. They are 1/4-board and screws will just pull through them...

You need to hit a stub or best bet is to install a back-board of 3/4 board across the wall where you want your shelf.. If your back board doesnt tie into any studs then perhaps you can use what they call MOLLY BOLTS in the four corners. These spread out behind the wall and give great support strength...


Then you can just use regular screws to mount your shelf into the back-board...

Something along this line of thinking like this HDTV is mounted...

You have to be really certain no electrical, plumbing or duct work is behind the wall and make sure you tie the shelf support into the framing for the wall.

On my RV I can look in different compartments and cabinets to see where wiring, plumbing and duct work goes. I can then judge if there's any of these in the way where I want to get into the wall.
