I have the 3 gun one(can't remember the name) that fully encases the guns and runs along the back of both front seats of my crewcab F-150. Put it in 3 years ago and it hasn't left. Very handy for not only guns but fishing rods, shooting sticks etc. Especially glad I got it now that both of my kids are hunting this year....
It's similar to this one.....
