Our A/V equipment cabinet that houses the satellite receiver and switcher boxes has been an on-going problem from day one! Actually, more than one problem!
Problem 1 was that the equipment would slide around while we were traveling, everything getting out of position.
Problem 2 was that the wood trim on the bottom of the cabinet door was blocking the IR signal from the satellite remote control.
I wanted to have some cushioning between the satellite receiver and the floor of the cabinet, so that ruled out Velcro, etc.
My first step was to cut some foam rubber to raise the satellite receiver up enough so the IR signal would not be blocked. I had some pieces that I could stack to get the required height instead of going out and buying a thick piece. I cut those to size and used RV Goop to stick them together.
I couldn't set the satellite directly on the foam rubber because it would block the ventilation holes on the bottom. I cut a piece of Luan paneling, which is only about 1/8" thick, about an inch larger than the base of the satellite receiver. I used the RV Goop to glue the board down to the top of the foam rubber stack.
Finally, I cut a piece of the non-slip shelf liner material the size of the board and again used the RV Goop to stick it to the board. I believe the equipment is heavy enough that it will not slide at all sitting on top.
The last step was to glue pieces of the non-slip shelf liner to the switch boxes on top.
I haven't been on the road since doing this, but I'm pretty confident this will solve the problem!
