looking for a build plan for a 250 gallon reverse flow smoker. with propane burners.

i have my trailer and my 250 gallon propane tank up at the welders shop right now. considering my location in northeast Montana, smoking wood is limited and expensive. i am starting a bbq food truck. so i need my smoker to be efficient as possible. any ideas or examples would help thanks.
