Looking for advice here. Looking to floor mount a bracket like this (See link) in the middle of the truck floor near the 4x4 shifter. Whats under the floor that I am going to hurt? How long of screws should I use and what type?
Thanks!

A less than ideal way to mount radios. Drilling through the floor of any vehicle puts you at risk a number of ways…
-rust. If you do go this route, make sure you seal everything up really well.
-risk of hitting vehicle wiring, you'd need to visualize what's under the carpet and what's on the underside of the vehicle. Running a self drilling/tapping screw through a wiring harness can be a real mess.
-risk of long screws hitting transmission/transfer case. While unlikely, the vehicle body does move a bit in relation to the frame, it's why there are usually some sort of flexible body mounts. You don't want the transmission hitting the screws.
Done right, it can work. My issue with self tapping/drilling screws is that they can come loose with time. Might need an occasional tightening, or replacement if they ream out the hole too much. Through bolting with stainless steel hardware would probably be the route I'd choose. Use fender washers on the underside as well as a good layer of RTV or some sort of sealer under the washer.
Preferably you'd might want to look at hanging this under the dash if that's an option. Back up the underside with something like aluminum bar stock to spread the load out a bit. Might help keep it a bit more stable on bouncy roads.
The floor transfer case shifter might be in your way, so getting creative might be required. I just installed two remote heads under the dash of my work F350 that has the floor shifter. I went from under the dash with a custom fabricated bracket.
