My AluCab leaks like a ********. Leaks through the rubber trim around the window glass (front window and back window). Leaks through the rivets that hold the roof rack tracks on. Leaks around the perimeter of the side doors. And the gap between the tailgate and back hatch was big enough to put my hand through. Dust doesn't even have to try to get in. The locks freeze, which wasn't a big deal, but the latches also freeze which is a pain in the ***. Plan on buying a tube of RTV and extra foam rubber bulb material to chase the leaks with. I picked mine up at Adventure Ready but did the install myself due to the shop guys being at SEMA. Tom was helpful and wanted to make things right, but part of the problem was on my end as I live a couple hours away and was leaving the country for a few months, so I couldn't really give them the opportunity to make it right. I've heard that they do good work, but most of the leaks I've had weren't obvious until we had a few good rains.
I was a bit bummed at the amount of work I had to do to make it right, but I'm handy and it wasn't the end of the world. I went with Alu Cab because of their construction and the vertical back hatch. There is a large section of bed rail that is exposed due to the bed rails tapering, which is a bit annoying cosmetically, but I found that it's possible to use that part of the bed rail to climb up onto the roof of the canopy, which is pretty helpful.
I'm also not sure what they used to coat the canopy, but it is super slippery when it's wet, especially the roof.
Oh, and of you already have Yakima roof rack stuff, their landing pads that are meant for roof tracks will fit the Alu Cab tracks. If I'd known this beforehand I probably wouldn't have bought the AluCab rack.
Also, why is gray a special order now?
Would I buy another one? Yes. It was honestly a bit of a letdown to have so many little issues though.
