Guys on TundraTalk swear by them. Would have been what I went with, but my Tundra came with underseat storage from the the factory.
Want one for my tundra. Waiting for feedback as well. Every time i have to brake hard i have to push stuff back under the seat.
Received an early Christmas present. Apparently the box was to big and my wife didn't want to wrap it. Initial thoughts is its pretty good. I'll have more comments once I get it in the truck and play with it a bit more.
