Rebuilding my Smoker

I have doing quite a bit of reading on a better designing a better Smoker.

I have what would called a Homemade Offset, Reverse flow smoker.


It started life as a pair of steps.






And it turned into this.








Now I do plan to add some angle iron to the firebox and tighten it up quite a bit.

I am kicking around some other ideas.

What would you do to improve this?

I have found some latches that will hold the door much tighter.

I also am looking at a DigiQ system.
