A picture of a hand holding remote car keys pointed at a white pickup truck. Below that is the text:
In the US, 75% of truck owners tow only once a year or less. Nearly 70% of them go off-road once a year or less. Additionally, 35% of truck owners haul something in their truck beds once a year or less
I am a fleet manager for a company that solely delivers them. However we know people will do this. It's your gas, but there is a reason there are many regulations for when gasses are transported. Things can get ugly really fast if anything is not right.
There was this incident in my town a long time ago. I believe the cause was leaking gas bottles and having them unsecured caused sparks, which then resulted in the explosion.
Milk crates. I was trying to come up with some way using wood blocks to hold propane tanks in the truck bed, then I discovered the milk crates the previous owner of our house left. They work GREAT for 20 lb and 30 lb propane tanks. Easy to strap in, as well.
I don't know why someone would want to carry a propane tank in the cab of their vehicle, unless they absolutely had to. I know I did it many time before getting a pickup, putting the tank in my car, and making the trip as short as possible.
