I am building this smoker, I plan on putting it on a trailer. I have a propane tank off a fork lift, but I think this is much to small to power this brute. I may go back to the scrap yard and get a second tank and weld together to make a longer firebox and put two or three four inch ducts to the smoke chamber. Or maybe just look for a different tank all together.

WOW with the two wheeler sitting there the tank shows its size. When it was out front I sure didn't think it was that big. Have you ran the numbers on the pit calculator? You can enter the tank sizes you have and it will tell you what size you would need for the air openings.
You may check online at a volume calculator site and see just how much smaller the small tank is.. I think most try to go with 1/3 smaller for the fire. Now that does not mean 1/4 smaller would not work. You may have to tend it more often tho.
I have been wondering if a tank like yours would work set up like a UDS. Have the basket in the bottom, only difference would be the door vs a lid. You would loose alot of heat when ya open the door but heck if your lookin you ain't cookin.
Just a thought.
Good Luck and pls keep us posted.
I guess it would have been nice for me to leave the link to the pit calc for ya. Sorry bout that, here it is.
This is the one I have used for volume in the past.
I went back and got this air compressor tank. It looks more proportionate to my firebox. According to the calculators I would need 40 gallon tank. I think I am going to settle with this one. Tomorrow I will run the numbers and figure out the size of this one. It looks to be about 25-30 gallon. It will easily tank more than a 10 pound bag of charcoal. I will put two four inch pipe from firebox to smoke chamber, then run the smoke stack on the outside and run through the wall down below the half way point.
I worked on the firebox all day, I ran out of rebar for the grate, but homedepot is a short drive. The pic where the firebox is standing up is the trap door/Air inlet. This should make ash removal a snap and provide all the air I will ever need.
The calculator says I need a 18" 4inch smoke stack. Is that the minimum or can I go bigger? I want to run it on the exterior all the way down to the bottom rack. This should cause it to hold more heat and help with the small firebox. Or it might not.
Here they are, I took a non-plated log chain and split each link and welded those on rebar. I made three rebar/hook bars and welded those in the tank. Then I made a triangle to hook to the rebar/hook things. Then I put some wings on the side to support 1/4 in round stock. Now it looks like a lopsided Star of David. I just bought the 1/4 in round stock to top the four shelves. I hope by the end of the week, I will have that done. Then it is on hold until I find the trailer to mount all this on.
