Carrying extra propane tank

[Outbackmel]

?? what is the best way to carry an extra full 20 lb propane tank in the bed of a p/u carrying a fifth wheel? I was thinking of just securing it in the corner of the bed behind the cab and wrapping the lower half of the tank in "bubble wrap" to prevent any banging around. I plan to use a "ratchet" strap to secure it....

danger? experiences....comments appreciated.

If it's dangerous, I'd rather just leave it behind.....

Tnx
