Easy storage of Scepter water cans inside the bed?

Looking to secure a couple 5 gallon Scepter water cans in the bed of the 2019 longbed. It seems like between the cab and the wheel wells is a good spot?

I see folks hanging them off the tailgate, but does anyone sell good restraints or mounts that go IN the bed?

Thanks, yall!

 

Not exactly the same but I put my water right there in the blue jug. I apologize for not having a better picture but I put one of the stock toyota bed cleats in the rail then run a cam strap over and around the jug from the cleat to my bed stiffener.

It takes up the little useless space by the inverter plug and the jug doesnt come flying out.

 

You can see it a bit better here best part is that its a free solution that takes no time to setup and break down

 

Take a peek at the smaller Scepter jug from Jeff Bezos......tan & $36
