My luckiest experience was on the way to Goshen this year. Enough time has passed that I feel that I can tell on myself now...
After reading how everyone thinks it's OK to run the fridge on propane going down the road, I decided to give it a try. We rarely
use the propane system in our unit, so I had to purge the line out. I figured the best (quickest) way was to just run the stove burner till it lights and then try the fridge.
Once the stove was going nicely, I turned on the fridge, hear a few clicks from the igniter and she was off and running. I turned the burner off on the stove, lowered the cover and after throwing a few more things into the truck, we were on the road.
Somewhere near Chicago (about 5 or so hours in) I needed fuel. As is my custom, I just popped into the camper to make sure everything was riding ok. The first thing I noticed was that it seemed awful warm in the camper. I considered cracking the vent open when I noticed the distinct smell of hot metal. I look around than that's when I noticed that I did NOT turn the burner off, merely turned it to LOW. I dragged my camper across the whole state of Illinois with THE STOVE ON!
Most people worry about leaving the stove at the house on. I did it in my camper. Thankfully, there was no damage, other than the lid for the stove is discolored. I can only imagine going to change lanes, checking my mirror and seeing a gout of flame coming out of my kitchen window. I bet you would have seen the quickest "Stop and unhook" maneuver ever performed.
