Not a good idea, particularly when refueling. I wouldn't do it, but many do, and that's why I try to avoid refueling when there's another RV/motorhome at a nearby pump island. I'm never in that much of a hurry.

HMMMM building codes allow gas hot water heaters in garages provided they are at least 18" above the garage floor. I'm guessing they think there might be gas fumes or gasoline stored in the garage. Just an FYI before all the internet horror stories start.

HMMMM, what do building codes about water heaters in garages (btw, they're water heaters, not "hot water heaters". If the water is already hot, it doesn't need to be heated) have to do with refueling at a gas/fuel stop, with active ignition sources in your vehicle(s)? Take your time, I'll wait. :C

I believe his point is gas vapor is heavier than air and tends to stay low to the ground. A home water heater has to be above 18" in a somewhat confined space to reduce an ignition source. Most RV fridge ignition sources are 36" or higher in open air. The chance of an amount of gas vapor large enough to ignite reaching your fridge at an open air, outdoor gas station is extremely small. Just because you can smell gas doesn't mean it's at a large enough concentration to burn.

My house water heater is inside the house, not in the garage, and still has to be at least 18" off the floor with an adequate drain pan under it to meet code.

As far as traveling with the propane and fridge on, think about it. If it was a true hazard DOT would outlaw it. It's already outlawed in certain conditions such as traveling through a tunnel or on a ferry. The rapid release valve on the tank should shut off if my gas line breaks. If DOT doesn't see it as a hazard, why should I?
