Please, replace those tiny fire extinguishers that come with the RV. We had a 2014 Road Warrior, and lost it to fire last summer. ( electrical issue ) It was parked in our driveway, plugged in as we were in the process of cleaning it after a trip. We spotted the smoke coming out of the kitchen vent, no flames at that point, called 911, fire dept here within 10 mins. My husband used the fire extinguisher that came with it, but it quickly ran out. In those short minutes, flames were shooting out of the roof. Both the fire chief and fire marshal said those tiny ones are just enough to get you in trouble.
We now have a Voltage, first thing I did was test the escape windows, then replaced and added more fire extinguishers. It was a scary thing to watch.
