I found many of the large drawers in RVs have flimsy bottoms that bow with any weight. I thought I would share a fix that one of my RV friends showed me. First take the drawer out, flip it over and make sure the bottom sheet is in all in the grooves of the guides on the sides, front and back if slotted. Then take a hot glue gun and run a bead all the way around the bottoms seams of the drawer inside corners between sides, fronts and back. I often put a reinforcing wood slat in the middle of the draw bottom if its a big drawer or flimsy. Hot glue between the bottom and the wood reinforcing slat. Put a nail or screw in each end of the slat into the drawer front and back. Also hot glue the edges of the slat. Often times we will use wood paint stirring sticks, that you can often get for free. I just did the drawers in my MH, before any of them broke. The center support is newly added in the picture and they help stiffen the drawer bottom. Hope this helps anyone with the same issue.
