Help with propane connection to external cooker

I've found the best way to secure a propane tank in the bed of a pickup is to use a Milk Crate. They are the prefect size to slide a tank into. Then I chain the tank,, not the crate,,, securely to a mounting point in the bed of the truck.

You don't want that tank sliding, or rolling around.

You Especially Don't Want It Flying Around In a Accident !!!

Chain it down.
