Here in Thailand it’s hard to find anything. Most of the time you just haft to have it built. Found it’s easier if you have pictures of what you want. Even then your chances are slim. So I searched net for propane smoker. Nothing fancy but size I wanted.
Box frame 1 1/2” tube steel, 2’X2’X5’ tall. Wrapped frame with 2MM steel. Room for 5 racks but because of question of cost only had 3 made. Small propane single burner in bottom with electric starter, was cheap but effective. Ran stack through roof of my outdoor overhang with adjustable vent. I used one of the wife stainless steel bowl for chip pan (she wasn’t happy with that but to late) fired that baby up and with the help of all in chat turned out some fine food. Total cost for everything=$400 Just need one more coat of paint then done.
