After looking at forum pictures I built my LP unit. I tried to do most of it from scraps and parts that I had in my garage already. 3 of the 4 sides are made with 3/4" untreated hardwood that I pulled from some pallets. The front is made from 3/4" plywood. The smoker seems to work pretty good so far. I am thinking about adding the mailbox modification that POPs added to his smoker. I added wheels and a side vent to the finished unit.... Pretty heavy.
