I didn’t order the Mopar Trail Rail, but Jeep has graciously predrilled the truck bed for the accessories. You can get all the supplies at your local hardware store for $60 and build in your own option. It’s galvanized steel, and supports a TON of accessories. I will eventually paint mine textured black when the time allows and the temps are warmer. This fits perfectly under my weather tight Gator USA tonneau cover, and should do just fine in the weather.

What size is the thread on the bolt? Great idea !
Have you been using the rails? How is it working?
FYSA if you ever look at installing a rack that mounts to the trail rail you might want to swap out for the square Unistrut it it fits great. You can see a pick in the DIY section on the Jeepgladiatorforums dot com
do you have a parts list? can you show the clamp from the gator cover and more of the install/finalized product?
