Well, tecnically it was yesterday I finished up on it, but I got my Retrax Powertrax Pro MX rolling bed cover installed on the new truck. I searched and researched for almost a month before I settled on a Powertrax. I bought it on the last day of the 10% off sale. $2,599 regular price. I managed to save $259.90. Took a bite out of the budget. But it has sealed rollers, a 3 year warranty, and it's made rather sturdy and sure seems like a quality unit. Hopefully it'll last a long time. I think it can hold about 400 lbs on the top (evenly distributed they say). Dang thing weighs a bit over 100 lbs assembled and getting it into the truck pretty much by myself was a PITA. You have to assemble the rails on the canister unit first then lift the whole thing up into the truck. Umph! Wife "helped" but she more or less guided it rather than help lift it. But I got 'er done.
Routing the wiring from the battery back to the unit was fun. I can confirm the 2020 Sierras have the frame wax as well as my old 2010. FUUUUUUUUUUuuuuuuuuuuuuuuu....k!!! That stuff sucks to work around.
I had a bakflip on the 2010, and it was nice, but this bad dad is the cat's azz! I think I'm going to love it. Eats up a little space in the front, but not terrible. It has a fob control to open or close it (no manual way to do it though if your battery craps out) but you can mate it with the Home Link buttons on the overhead console so you don't have to have the fob with you 100% of the time. Got to do that yet, but this is LOVELY. The wife likes it because she's not tall enough to operate a manual Retrax very efficiently, so it's good for her should I ever allow her to drive my truck!
