Oh, this is blasphamous. Using Propane to smoke???? Charcoal and lump all the way.

Just kidding. I use a weber bullet and kinda wish I could get a propane. I love the idea and taste of lump, but its difficult to control over 16 hour brisket smoke.
Here you go, they use charcoal or propane:
Masterbuilt 7 in 1 smoker
I have their 25# mini version and it works great, for lump flavor just add a foil packet filled with lump to the base occasionally, chips or pellets work well too.
