Thats also a requirement, I has to be a crew cab or full size cab. Not sure of the correct nomenclature Nissan specifies theirs as.I say go for its a great all around truck easy to service an hella reliable. If you dont with the longbed you could go kingcab since it has a longer bed than the 4 door.
So I wont be able to get a full size bed with a full size cab. Thats fine as long as sheet good can lay down flat between the wheel wells. So with the tail get down, the material should not hang past the gate right?
