Those stove and oven controls on the front edge of the stove can easily be turned on inadvertently without knowing.
I'm surprised some appliance company hasn't come up with a flip-down safety cover, to help prevent bumping the knobs when walking by, or positioning them into a recessed panel, so they're less likely to be bumped.
I have woke up in the morning after sleeping all night to propane smell in the camper. A friend was sleeping on the dinette bed. I did not smell it in the night because I was up high in the over cab bed. I smelled it once I got out of bed and climbed down to the main part of the camper. The stove was right across from the dinette bed. I and my friend are both very lucky he did not suffocate to death in his sleep!!! :e
Another time, I had a mountain bike inside the camper that I had leaning against the counter cabinets in the center aisle. The bike must have moved some when I moved the truck and bumped the stove knob. I had left the camper and when I came back, I opened the door and immediately smelled propane. Fortunately, I am not a smoker and didn't have a lit cigarette in my mouth when I opened the camper door! I could have blown the whole thing up, and myself too!
I think in my next camper, I will re-route the propane hose going to the stove, so I can install a ball shut-off valve in the stove line only, in a place that is convenient to operate the valve. This way, I can safely leave the propane on, to run the fridge, furnace and water heater, and shut off the propane going to the stove, so I have no worries that the stove/oven is leaking propane into the camper from having bumped the controls without knowing it.
