for what is worth, it would probably be a real PITA to get this to work on our trucks. I once saw a post on my FJ site of a guy who didn't get one in his FJ and wanted one, so he found someone to trade his dash, for one with an inclinometer. They met and took pictures of the exchange. They both literally had to rip apart the entire dash/console/everything to do the exchange; it looked like both their interiors had exploded. Not an easy job if you don't have the existing wiring, even if you have an FJ w/out this option.
I thought about this as soon as my neighbor got his FJ last summer. It does look sweet.
