Anyone installed extra d-rings in their toy hauler?

Has anyone added d-rings to your toy hauler floor? I'd love to hear about your experience.

I would like to add 2 or 3 d-rings near the wheel wells, but I'm told it's not recommended because I might "compromise different components." I know the fresh water tank sits under the floor, but I'm curious if anything else might be running through the floor (ie wiring, etc).

Thanks in advance!
