This is an old smoker that I built outta scrap iron that the bossman gave me. A few years ago. I have since converted it to reverse flow and lately I added a verticle attatchment. I used a stationary mount LP tank[22gal I believe] and the fire box is 1/2'' steel plate The verticle box is 1/4 '' plate. hinges, home made and just about anything else is too. except the therms. Most of the ones in the past were trailer mounted. Usually gave them to friends because I got tired ofmoving them around. This size is what I found to work for me. Just me and the wife and a pair of eatin' machine Rotties.. We don't entertain and we don't visit.. I been stealing recipes and Ideas off this site for a WHILE now. Thanx, Folks I don't post much and have quit with the advice thing but I ain't really anti-social. Just we are pretty private folks.. Take care.. Hemi..
