I wouldn't think it likely, but will you get water through the bolt holes when you cross the river?

2 bolts won't be enough to hold the box to the floor if you go upside down. You'll need at least 4, & the heads should be on 1/8" steel plates at least 4"x4" to distribute the load.
another easy solution would be to use 2 U-bolts. One on each side, through the wheel wells. You would have a little bit of thread and two nuts on the inside of the box, but not much. Bolts in the sides would likely hold the box better than through the floor. Doesn't require welding. The U bolts shouldn't affect your tires any unless you've got a lot of rubbing already.
Just another approach that might work for you
I bought these last year from a Ebay vender.....sadly long gone but looks like you still have room for a set

That looks like it will hold alright! Good thinking. You might consider using a nylon insert lock nut underneath. It has been my experience that the road vibration can loosen any nut. Just a sugestion.
