Tailgate Lock

I'm looking to add a tailgate lock to my 2001 Ram 1500. Just wondering if anyone has any input on what brand to get and if there is any advantages to one over another. Thanks.

I bought a "Bully" brand off from Ebay. You need GOOD torx set to set to get the screw for the lock out. My torx bit failed pretty quickly and I used a chisel to snap it in half, not exactly the ideal method. Also make sure you have the key in the lock when you are installing it in the tailgate or else you will drop it inside the tailgate which is very aggravating. The latch bolts are impossible to move so I didn't install the latch guards.
