Oxygen and Acetylene bottles I haul laying down strapped down .
And I see the pipe liners with them at a angle mounted to there trucks so I don't believe they have to be standing up to use them .

Only acetylene has to be standing upright because there is liquid acetone in the cylinder that you don't want to be drawn out. Propane has to stand upright too since it's a liquid in the tank. Oxygen is a gas so it makes no difference.
