You are 100% correct!is the vent for the LP at lowest level? If not you need to do that. My understanding is LP is heavier than air and will sink and accumulate giving you a potential for little leak to become a big nasty explosion. From what have read vent for stored LP must be at lowest point possible and that whole area must be air tight from the cabin.

Thanks, but I'm not so sure about the "heavily educated" part, but I did learn a few things in the 30 years I worked there, plus I was fortunate enough to be able to attend various in depth schools at places like Florida State Fire College, LSU, University of Alabama, Texas A&M, etc.Thanks Pat. Was hoping you would Pipe in (pardon the pun). Had remembered you were heavily educated in all things fire related.
