I recently installed the ESI seal on my 2021 Lariat to accompany my Gator EFX tri-fold tonneau cover. A rather odd combination of pieces around the bottom corners of the tailgate but it seems to be effective. The most challenging part is along the sides as there is a very tight margin to obtain an effective seal without the side of the tail light causing the material to roll. I ended up supplementing the side seal piece on the tail gate with a couple pieces of 1/4" black foam window molding along the inside of the tail light lenses. The ESI piece presses back against it and makes a good seal. I also put a tiny bit of black sealant on each end of the short piece filling the hinge hole on each side.
I think with my small tweaks it's pretty watertight. Ran it through the pressure washer and there was no trace of moisture in the bed. I haven't detected any dust intrusion either, though I haven't yet given it a rigorous test.
