Keeping Dust out of a Project M Popup Camper | Installing a Tailgate Dust Seal

I used the “Ultimate Tailgate Seal with Taper Seal Installation for 2015 and newer Chevrolet Colorado & GMC Canyon kit“ which I bought on Amazon for $31 including tax. They have generic tailgate seals but I liked this one because it fits like a glove and should keep most of the dust out. Looking forward to my first dusty road to see how it does. Update: Just did 10 miles on a dusty road, worked great, no dust inside!!!!!!!!!!!!!! Back window and tailgate covered in dust.
