I've always been satisfied with my hard top in winter and no top in spring-fall, and have always wanted some sort of roof rack to stow gear as well, but that would equate to a winter only operation...
This thing is an AWESOME (long overdue) product! If it's as airtight as Chuck says it is, there might be a lot of steel tops on eBay pretty soon because this could work year-round!
I'm hoping that it's affordable to the "regular" guy! If so, I'm driving though the Mojave to be at Chuck's front door as soon as it's available! (or at least mass buy here, but still go visit)
(Did CanBack mention
color availability?)
These are good times.....
