Several years ago, about 2004 I think, there was a class C fire at a gas station in the Town of Frisco, Colorado. A couple of cars and the OH canopy along with the RV were destroyed.
It was said (rumored?) the cause was a faulty gas fill nozzle that did not shut off. The user pulled out as it was still dispensing gasoline which sprayed all over the side of the camper. It was also initially mentioned that the side on to which it sprayed was where the refrigerator was located.
There were reports of station maintenance crews doing work on site which may have caused gasoline and/ or gas fumes and early speculations were indicating something "RV related" added to the ignition. Perhaps just coincidence, but the RV was certainly involved in the fire.
I have e-mailed the local fire department a couple of times to obtain an official position of the investigation on this matter but have not heard back.
I may follow up again with the local FD to try and find a final investigative report.
