I would suggest Pm-ing, Orlen Wolf he's a member of fiberglassrv,com and owns a EggCamper
. If I remember correctly he added or had propane
added to it. Can be done if not by the manufacture than by a propane
Sorry I don't know the technical name but I know it can be done. My Mom had a caddy when I was in high school that ran off propane and I know it didn't come standard........ At the top of this page you click on (community) scroll down to member list and find Orlen Wolf send him a pm he should be able to help you figure out how to do it....... Good Luck!
