I have a Humphrey Gas light near the entry of my trailer. It makes a lot of light and uses very little propane.
Likes: Saves battery when dry camping, very energy efficient, looks cool, nice bright light, small additional heat source for chilly evenings
Dislikes: sock is difficult to install, disintegrates from vibration ( gotta have that running gear balanced, right Andy?) get s hot to the touch, additional heat source when dry camping in Baja where it is hot to begin with, additional gas plumbing is also an additional source of possible gas leaks.
There are websites, like this one, where they have the classic Humphrey lamps available for about $ 70.00. They work great, and i believe they are the best. Mine is 30 years old and still works perfectly good. Order extra mantles........
