Trying to build a smoker and not having much luck finding a pipe or tank. Looking for 30" x 5'-0" (for cooker) & 30" x 2'-0" (for firebox) Or a 250 gallon propane tank that is close to the above dimensions. First attempt at a trailer build and any help will be appreciated. Located in NW Illinois. Thanks in advance for any info to help me get this project going.
