Truck rifle carrier

[graham1]

Hi folks.
Im curious what everyone is using for holding long guns in the truck.
I have a 2018 crew cab so often the rifle is on the back seat on the way to the hunting grounds. Which isn’t really ideal, but doable.
The real issue comes when my son and I are headed out after birds.
2 guys, 2 shotguns and an excited chesepeake on the back seat.

I have seen cabelas and others advertise a stand up rack more meant for side by sides and I’m contemplating buying one to try to mount in the pickup.
Maybe there’s a better option?

I miss the days of them in the back window
Thanks
