Re: what is adequate ventilation for propane tanks
Propane is heavier than air - so nothing that has the chance of holding it in. Something with a grate on the bottom (I can't remember who did that, but it was effective looking). On my bus, I carry a little more than 60 gallons - there is one 83 gallon tank but you have to leave a percentage "empty" to allow for expansion when it heats up. My bus runs on propane, so my tank is mounted under the bus, between the frame rail and the side skirt, and is in a tank strong enough to take a pretty fierce hit (it is designed for vehicle use). Any leaks drop straight down and away.
I am in the process of adding an under the bus compartment that will hold two of the 5 gallon (20 pound) barbeque bottles for the stove as well as part of my renovation. I'm going to use expanded metal mesh for the bottom.
