You would need to know how much 'power' the inserts have. You may need more of them than you think. Also check under floor to be certain you don't drill into something important. You may have thought of this and other things, just the first few that come to my mind. (my gas tank is under the floor)
Thanks, yeah and those inserts/screw will have lateral movement as well and straight up/down. I've seen some that claim 40,000 lbs of tinsel strength. I suspect they are talking about the insert itself, not including the mounting. Also, I suspect that any rating will be based on a straight pull or push not side-to-side rocking, and vary depending on the wood its installed into. I looked at some of the install instructions for those things and they suggest filling the hole with epoxy before screwing or dropping in the insert. That seems like a solid idea as well.
