Brig, I've got a contact you should check out for your SuperCrew. I've got one on my SuperCrew. It's a Retrax retractable bed cover. There web site is www.rolltopcover.com. You can call their toll-free number 1-877-Rolltop and ask for Tim.
I am also looking for a cap for my new SuperCrew. I believe I finally found one that is not your typical chunky type. I got a brochure by Jeraco. Look at page 4, the Standard Deluxe Series. The blue one on top. It has a higher cap and really looks nice. I don't know if there is a website for this or not. But its Jeraco Enterprises,inc. Good Luck.
I did a ton of research, wanting a cab high, lined, electric wired, locked....the whole deal.....I didnt like the straight lines/looking like a box sitting on the bed etc.
found the Raider (Vagabond model), they are made in Canada.
I love this cap, as I stated, cab High and an awesome fit to the lines of the Supercrew, both the slope of the cab as well as the slope and angles of the bed. Cab lines are matched about as good as you can get, in fact people ask me if I had the truck custom built, but then I break it to them that its only a cap!
Looking from the back of the truck, the slope of the truck bed is continued as one smooth line, color matched and the sides extend beyond and cover the Ford Black plastic rails, so they are completely covered up from view. I had a Rhino (grey) liner sprayed in as well. Here is a web site that carries them, but do a search for Raider Canopies......you know the deal.
Good luck......oh......I paid $850. installed in Spokane Washington.
