If you can find this antenna, I'd mount it behind the cab window, in the middle of the bed. This was the best antenna I have found as of yet. The oil cooler helps a lot when boosting power. And it was almost fool proof to tune. I ran skip on my galaxy from Dallas to Maine, transmitting and recieving. Granted it was about to snow and te atmosphere was just right. But the farthest I've talked on a fire stick was Arkansas. Although the fire stick was decent and more than enough for trail use.
Big thing is don't let your coax cross over itself, big bends in the coax. And I recommend 18 feet of coax minimum.
Mount it like this guys, but up against the cab, between the tool box and window.
