Thanks! Yeah, I did install it myself in my driveway.
I guess, I just expected it to fit perfectly for $1379+tax. I think if it was a little longer, maybe .5 to 1 inch longer it would cover the tailgate and bulkhead. Also, the vinyl cover that sits on the tailgate should be rounded so it fits...
Did I install BAK X4S incorrectly? The directions say to align the vinyl cover with the front of the bed but if I do that then there is a large gap at the tailgate. So I did my best to align the tail since I the flappy part at the front covers just fine. Also, I could not get it to be perfectly...
