>>The propane bottle inside the car is fine, infact the Europeans seen to
prefer  a bottle in good condition inside the car over the American method
of a rusty  one with defective auto shutoff valves on the outside.<<

Over the years, we have carried two different smaller sized bottles... and
both have leaked in the car after filling -  while driving.  I find even the
tiny non-refillable bottles leak a bit over time if they in the car.  After
a while you notice a not so nice rotten smell inside the van... propane
really stinks in a closed compartment, not to even address the safety
aspects of any bottle left inside these air tight boxes.

We tie ours onto the luggage rack now - always outside!
