I was waiting for the XT model of the F1 but with Bakflip recently acquired by another competitor. There is a one month delay for new owners to evaluate new product release. Morrie already had offered a great deal on the F1 XT, but he offered the standard F1 at a great price so I could have my cover for TRR14 and get the upgraded rails at a low cost when available. The F1 installed easily and works very well. It rained a few hours after install, checking after rained had stopped it was bone dry inside. Thanks for great service and quick delivery Morrie !!!
