No way to lock the tailgate. To get in someone could basically just rip open the tailgate.
I'm gonna make it harder for them.
Keeping honest people honest since.... Um... A while.
Step 1: I Need Chain. and a Hookie Thing
Step 2: These Are the Tools You Need to Remove the Bolts in Your Bed
The last 2 are to bend the chain links
Spray on bed coating
I use rust-oleum
Step 3: Take Off a Link.
Step 4: I Painted It So It Would Match My Truck
Step 5: Cut a Length of Chain and Bolt It to the Tie Down
It's that simple. In the second pic you can see the length of chain on the tailgate too. Where the clip will attach when your tailgate is "locked"
