So I received a free used propane tank that I am going to work in to a RF smoker. I've owned one in the past and switch to a BGE but want to go back. The BGE doesn't provide the flavor profile that my RF smoker provided. I have access to some galvanized pipe that I was thinking about using to build the stand. It would not be in the cook chamber or touching the firebox. My plan is to build a simple saw-horse style support for the smoker. Okay to use galvanized piping in this situation? Seems easier to do than ordering steel piping online.
