Don't drill holes, try custom storage you design:

Depending on the age of your trailer and other things, I think you have 3 basic options.
  1. Git Rot the area
  2. Cut out and glass in a patch of the bad section
  3. Replace the floor in that section of the trailer.
All 3 have been done with many pictures posted here in the forums.

You will want to investigate the extent but also the source of the rot. In the case of my Trillium, there was some rot but only immediately around the screw holes for the straps that held down the tank. Easy fix. Had it been more expensive I'd have replaced the plywood in the area affected and recoated it with resin. It's important to keep this area of the floor strong because in my case the bolts that hold the body to the frame pass through it.

Thanks folks! repairs are underway. I fixed the long ago. It was a rivet on the roof that gave me a fit to find. I found a piece of laminated oak that is actually lighter than the 3/4 OSB for the repair.
