meneco, I found it very simple to disassemble the burner tube and give it a good cleaning. A couple screwdrivers, end wrenches for gas line fittings, and a small wire brush are the tools needed. My Norcold quit lighting after 8 or 9 years, and after I cleaned it, it lights easier than I ever remembered. There are slits cut into the burner tube where the gas exits and where the flame is. On mine, these slits were completely plugged with black crusty build-up. I picked it clean and shined it up with a wire brush. I didn't take pics, but I'm sure if you ran into questions you could post here with pics, and folks on this forum will walk you through it. Go for it!
Those DC units are the way to go, but they are pricey.
I also drive with propane on. Never had a flame-out.
