Hi all, I'm replacing some rotted flooring in the middle of my RV in front of the kitchen and slide area. When I removed the flooring I see the support beams are like a 1 X 2 made of metal. It's weird to me the flooring is only glued on without any screws. It's about a 6 foot by 6 foot section I'm replacing so can I glue and put screws through the wood into the metal supports? I wasn't sure if there are wires or hoses in the cavity of these beams. Has anyone done this before? Thanks Ron
