& the helpful advice
What I originally guessed was a water tank drain, based on your info & closer examination turned into a gas lead

, but don't know as I'd be tempted to use a gas bbq that close to trailer or awning ?
Although along w/ other uncountable manuals, there's one for the included gas grill (uniflame model npg2301) in owner's booklet; I don't think it was orig equipment. It's legs are way short & it's designed to be used w/ those small throw-away cylinders
Wife of 41 yrs & counting & I live in town (but not village) of Canton, NY in St Lawrence Co. Not much NY N of here but plenty of Canada. Leaving in few wks to again spend many months snowbirding in AZ. Previously we did so in FL & will return to winter there but really enjoying SW @ present
BTW, like Sunline, we were both "manufactured" in PA
When we're home we spend lotsa time in Adks
