How to Transport a propane tank?

Explain firstly

about the heft of that item.

On wheels            

Make sure that it's strapped down on the vehicle.

Either I carry if I am walking, strap it to a horse if I am riding, strap it to motorcycle if that is what I got. I use the vehicle I got.  Wheelbarrow it.  Use the Lear Jet.  Really a vague question. Hopefully the answer is just as vague.

Assuming it's full and you're referring to a standard BBQ tank, not a larger one, I will put it on the floor between the front and rear seats ( with the front seat adjusted to secure the tank upright ), turn on the fan blower motor and lower the rear windows to vent the interior just in case the tank leaks.

I typically put it in my trunk and drive where I am going.
