I do not trun off my porpane. But keep this mind. Their is a flame and if you pull into a gas station it could ignite the fumes. You will get lots off people saying off and others on. At the end of the day it is up to you. How safe do you feel with propan on? I think there are far more with propane on then off. Ernie
Not to sound mean or anything, but we drive our vehicles with fuel in them. Yes, each type of fuel has its violatility and the posability of causing a fire. So, I will continue to keep mine on. My truck doesn't run unless there's diesel getting to the pistons.
