A buddy of mine has a GMC Sierra 1500 with the BackFlip setup. For my 17 Silverado 1500, I have the UnderCover version here:

I like mine better because of the panel materials and the "rhino lining" on the panels where my friends are still aluminum but painted or powder coated. They dent and scratch a lot more easily than mine. Otherwise the design is very similar and both are good products, but worth looking at each one to see what's best for your application.
