It's not attached to the tailgate but it could be, there are screws holding the cover plate on. I just slide the tailgate mat in and out as i need it. It is rubber and doesn't move.
Went to home depo and got a 4' × 6' rubber mat. I cut it in with all metal scissors to fit the bed and the rest made a nice tailgate mat. It only took 15 or 20 minutes.
I bought my daughter a 2020 EB in 2021 she has been driving it ever since. We have had no problems or break downs. The gas milage is great. I would buy it again.
I took both of our mavericks to the car wash last weekend. I looked all around for damage, did not find any. The only way to keep them clean in the winter.
