Fastening something to an RV wall presents some problems, but none that can’t be overcome.
RV walls typically are hardboard or paneling on studs or insulation. Neither surface holds screws adequately.
Here are some solutions for attaching to an interior RV wall:
Velcro keeps wall-mounted artwork stable and safe. Buy adhesive-backed strips, placing the “hook” strip onto the picture and the “loop” strip on the wall. Velcro should hold moderately sized frames and art in place even over unsettling bumps.
Although strong, this method is temporary. Simply pry off the fastened artwork, then apply an adhesive remover, such as Motsenbocker’s LiftOff, to remove the strips from the wall.
RV wall studs measure only 2x2, or smaller, not 2x4 like home framing. You may be able to attach directly to them. Locate studs with an electronic, battery-operated stud finder, available at hardware stores, home centers and online. Get one that finds not only studs but also electrical wires. A good example is the Zircon StudSensor e50, about $25. You can use this tool at home as well as in the RV.
Once you mark the studs’ location, you can use self-tapping wood screws to fasten a shelf or TV mount directly to them if the mount doesn’t span two studs, attach a strip of wood ¾-inch or thicker onto the studs, then attach the mount to the wood strip. Before attaching, turn the edges the wood with a router and dress it up with stain or paint.
A strong adhesive such a Gorilla Glue will mount light items, as long as you can find a way to hold the object in place until the glue sets. But beware: Removing the object my leave a marred wall, so be sure you won’t want to take it down later.
Pop rivets require, in addition to a drill/driver, a pop rivet tool, about $12 at discount or hardware stores, or home centers. They make a neat, strong, nearly flush bond and require smaller holes than an anchor would. You may need a helper to hold whatever you’re mounting:
As you squeeze, the mandrel’s inner end reshapes the body of the pop rivet assembly into a second flange on the inside of the wall, holding in place the object you’re mounting.
Designed for fastening to hollow doors—also found inside RVs—these anchors are about an inch long, which is shorter than the anchors used to attach to a home wall. The anchors come with machine screws that thread into the anchor. The procedure is simple:
As you tighten, the anchor will draw toward the interior wall, spreading out flat against the back of the interior paneling. That creates a flange considerably wider than the threads on a screw.
