I have three trucks with shells, and all are SnugTops. Good quality, relatively high price, crappy customer service (they force you to go back to a dealer). The "work" truck has Yakima crossbars and a Yak DryDock, and has carried as much as 1100 pounds in a single load with no damage to the shell even though the Yak bars bent. Also used to carry an aluminum bass boat up there with no problems. The "travel" truck had Yak bars until I bent them badly while bouncing around on bad dirt roads with a few hundred pounds on top. No damage to the shell. The "daily driver" truck has no rack (yet) but I bought the shell used, had it painted to match for $300, and it looks new. The only failure or maintenance issues on my SnugTops relate to the third brake light (they use cheap ones), the window screens, and the lock cylinders. My oldest one has been in heavy use for 21 years and is getting a little finicky to unlock. For me the only reason to get anything other than a SnugTop would be a screaming deal on something else.
