keeping things cold

My wife and I get meds in the mail or UPS with ice packs in them package. I have saved them for reuse in my rv frig. I simply place the ice pack behind or between the food, several on each shelf and things stay cold all day. we don't bring ice cream of fudge bars with us so we have lots of room in the freezer to refreeze once we are camping. has worked for us for about 15 or 20 years now. I saw what happens to gas stations when the frig ignites the gas fumes while refueling and I feel my safety and the thought of keeping my RV from burning up is important enough to do what I'm doing. Have seen guys on here say "So what? that is why I have insurance. Just about the dumbest thing I've ever heard. Scenario--your frig is running, several cars around you refueling. several have little kids in car seats. these kids are strapped in tight, like the law requires, and Bang the fumes ignite. the fire ball is large and how do you keep from panicking and get those kids out alive? good question. Maybe you do and maybe you don't. I don't think I could sleep at night if I caused a fire like that. Now many here are saying I'm over reacting, maybe I am. But like I said, I have seen the fire in a local station and it wasn't pretty. Hope you reading this will reconsider and turn off your frig at the stations
