I have looked at the racks that go in top of cab, saw one in GameWardens truck in Texas, I can’t do that to my trucks either, I do have one in top of 4 door Ranger, so in feed trk. It just like RBar says, grab and out the window, others I have Marathon seat covers with gun cuffs on back of seat, carry at least one long gun every where, tinted glass and towel or coat over ones in passenger seats, unloaded when on highways with clips close.
