Need some suggestions with Smoker re Temp Control for long Cook times.  I use propane to an old BBQ Burner with Cast Pan.  Start it with Propane and add Lump Charcoal and then add wood.  See Pics re size and vent info but keeping temp even is nearly impossible with 40 degree difference at top where vents  come out vs bottom where it exits.  I get a great smoke but I have to be VERY careful where I put stuff and I monitor temps a lot.  I know this big old thing takes an hour to get to temp but keeping it there is a pain.  When Outside vent quits smoking I have to tweek burner vents a lot or add more wood and keep smoking.  Some stuff I do I need a few hours smoke but 3-10  hrs of cook.  

Considering an oven temp control on LPG and thermo couple in exit plenum but afraid temp where smoke comes out at top will still be way too hot if I am trying to maintain 230 degrees or so.  Maybe a PID controller but $$ are high.  Love the size and how well this works but it's just a pain to manage.  I just did a small 4 rack group of ribs and while they were good they did get more cooked than I would like.  I use a modified 3 2 1 process.  

Maybe I just need to use the lower 2/3 of box??





  Smoker is on Concrete blocks and walls are 4" thick on sides with 2 - 2x9 openings for smoke to travel up.  Metal faced inside with concrete board behind metal then insulation.  Bottom and top are Steel with concrete board and ceramic tile face.

Suggestions appreciated

I use  a mix,   A propane burner from an old BBQ side burner with a Cast iron pan that I add Lump Charcoal to.  When it gets going I add wood for smoke and back off gas.  Just add charcoal as need plus keep wood in pan for good smoke.  I use vent adjustments to try and control heat.
