About to start my first smoker build on a 250 gallon propane tank.  Would like to build a reverse flow smoker with a warming box on top. I will be building it with my dad and we're not all about re-inventing the wheel, so if anybody has a great set of plans on how to put it together, that would be awesome.  I'm sure there are many different ways to put it together but I would just really like to get a good, solid, basic build that would also work for catering if need be.  Ideally, that would include mounting it on a trailer with appropriate sink(s), cutting board area, wood/charcoal storage, propane tanks and side burners.  We've seen some truly great rigs on the internet from builders around the country, but Warren Buffet we are not.  We're not professional welders, so it will take a bit to get her done.  I've learned probably just enough to be dangerous from the reading I've been able to do on the forums here and they are a great help!  I look forward to the generous help I've seen from browsing here and posting pics of the build along the way!

Thanks,

Tom
 
Wondering if it would be of any benefit to build the warming box with double wall construction and use insulation between the walls. Found some 1" by 24" by 25' rolls of refractory ceramic fiber insulation for sale on Amazon.  Vendor states it's safe for food service applications.  

Also wondering if there would be any benefit to doing the same thing to the firebox.  Saw where Aaron Franklin's youtube video for his non reverse flow pits shows a round firebox chamber inside another round chamber about 3" larger, but with no insulation.  He called it semi-insulated.  If there is a benefit, I'm guessing you wouldn't want to insulate the walls between the firebox and the warming box and just use the radiant heat from the top of the firebox to warm the warming box?  The design I'm thinking of would be a square/rectangle firebox and the warming box on top of it, with the smoke stack outside the warming box.  

Thanks,

Tom
 
Hi there.

It comes down to cost/time you need to invest in it.

If you live in a cold climate and plan to smoke outside it maybe worthwhile.

For me insulating the warming cabinet on a smoker for ocasional use is not worth it.
