I suspect it's the Factory Tonneau cover....soft Tri-Fold, the one you get as an option.Which cover?
@Slim , I'd wait. might be a pain to have one put on later, but it's such a 50/50 thing, the pros and cons on the soft trifold. I like that one person can remove it and install it. I don't like how it's clamped down from factory and as we've seen, it can literally blow off if you don't adjust it after delivery.
I would look at Truxedo covers if you're in the market for a soft roll or fold. I like their covers.
