Hard to tell but do you have the MFT? Won't the brackets that stiffen up the bed be in the way?
No way to install WITH the brackets. Shady that the dealer would remove them, since we've been told HERE on a number of threads that doing so would void the warranty if you run into issues with the bed down the road.
The dealers are apparently ignorant of this fact (as other members have reported the dealers taking the brackets off) - but will smarten up quick if there's any issues and FCA tells them they won't warranty the parts and labor. And if they DEALER TOOK THE RAILS OFF - they can end up being liable for the repair (especially if they didn't get the customer to sign an acknowledgement that removing them voids the warranty).
I was going to start a poll here, to see how many MFT owners just said screw it and took the brackets off to accommodate accessories that won't fit WITH THEM.
Cover manufacturers are "reportedly working on" units that will fit the MFT's - but a majority of even the folding systems require a rail that runs along the lip of the bed, flush with the bulkhead for the covers to sit in to maintain watertightness, and the rail also acts as a "rain gutter" diverting water into a drain tube out of bed.
I'm running a Gator Hybrid currently - which does fit - but it really wasn't what I wanted (prefer the bakflip MX4 or FibreMax - or - Xtang Encore).
