I had this cover for a few months on my 14 Laramie. Left it on there when i traded it because it wouldnt fit my new truck. Came from a BAK revolver x2 that was 7 years old and destroyed. I preferred the X15 for its very light weight, ease of rollup and complete removal if i wanted , low profile and great appearance. I liked the tension adjustment and how easy it is to snap closed and smoothen out. The velcro is seriously good quality and i can see it lasting for years. The cover material looked great, it rippled a bit in the freeway wind which is to be expected but never came free or loosened up. The bulkhead end fits flawlessly which is a big problem area with the X2 revolver. The new model X4 revolver didnt look any different in this regard so i stayed away from it.
Obviously i didnt get to see how it held up over time, or how it handled snow piled up on it, (something that doesnt happen much here anymore), but i liked what i saw enough to purchase another one for my new MY24.
This one will be a little different because of my Multi function tailgate, and it wont be easily removeable apparently, because of same. I ordered an extra tailgate end hold down clamp on amazon, because they only ever come with one, so we'll see how that goes. Im not sure it needs it, obviously the manufacturer didnt think so !
Should be here Wednesday and hopefully i can install soon. Ill let you know any wrinkles !
