Also, is it safe to run it on propane when traveling? Or should I stick to 12 v when on the road?
I always Light
mine with a butane firestick through the view port at the bottom. My piezoelectric button works, but as you say it is not clear.
The heat is more evident earlier if you touch around the back of the tube.
As for using propane on the road.... It is not considered "safe practice"
to do so, especially when refueling the tow vehicle.
That being said...survey after survey says that nearly 75% of RV trailer owners do run the fridge
on propane while towing.
I have seen a few burnt trailers, the total losses would be hard to call without close inspection, but twice I have seen localized fire damage and both times it was the fridge
. A third time I saw a trailer just pulling over with flames coming from the fridge
This small bit of empirical evidence degrades to anecdotal upon reading this....,there are of course hundreds of thousands [maybe millions] of trailers who do this without incident for years.
The problem sometimes occurs when an impact on a live gas line or a bump or vibration causes a disconnect at a fitting, releases propane which then finds an ignition source. This is a very rare occurence with dire consequences.
Another possible source is if gasoline fumes find an ignition source in your fridge while refueling. most states prohibit refueling with an ignition source nearby. They require shutting off ingition on vehicles at the pump before refueling and extinguishing smokes as well.
Just how great is the risk? People play the lotto against impossible odds, thinking they might "win". Is one in a thousand safe enough... One in a million?
You are right to ask the questions in order to make informed decisions.
I make it a general practice to tow with my propane tank turned off .
