I have been thinking on building a double walled insulated, gas assisted pellet smoker. It would be out of stainless and insulated with fire brick. The gas would be to bring it up to temp only and the smoker would then take over.
My thinking is that it could more easily be used in the cold and even windy condition.
Has anyone ever seen any such contraption?
I don't know what part of Texas you live in but it never gets cold enough in Houston to warrant such a setup.
Someone you may want to talk to who does have large pellet cooker experience in competition is CandySueQ. I know she hasn't been around lately, she's a busy woman but she may have some feedback for you.
Interesting concept. I think the dual fuel is worthy of discussion. I wonder about the efficacy of gas and pellets. My gasser and pellet pooper generally get to desired temperatures about the same time, and modern controllers can hold a pretty steady temp in just about any conditions. However, plumbing a gas sear station would be very nice.
No need to use firebricks between the stainless panels. Use something like glasswool ceiling insulation instead.
Firebricks are heavy.and not necessary for that kind of application.
There are several insulating companies I've worked with in oil and gas plants that can put high heat insulation with a light weight stainless shell over it on your cooker. I found a company that sells stainless barrels on line. As soon as my shop is finished I'd like to use one of those to build my own version of a barrel cooker.
Deep in the MCS zone.

Well, I've sort of been building an insulated gravity fed smoker for near two years now. I blame Nightrayne for not quiting his job and working on it with me more. Not that it's hard, just hard to find time. Need to get back into it. Anyway, you can get some rock wool batting insulation that is rated for 2000F. Shouldn't be any problems. That is what I'm using anyway. Few pics below. The insulation can be bought online. That image is from a website, but I'm using the same thing.
Started Low-N-Slow BBQ in 2012. Obviously, it's taken hold (in chronological order:
1.) A pair of Weber Smokey Mountain 22.5's
2.) #LilTex, a 22" Expensive Offset Smoker (looks like a Yoder Witicha)
3.) #WhoDat1, a HUGE Gravity Fed Insulated Cabinet Smoker (cooking chamber 3'x2'x6')
4.) A Full Size Commercial Dryer/converted to Vertical Smoker.
5.) Jambo Backyard stickburner (my FAVORITE Pit so far)
6.) GrillMeister, a huge 24"x48" Adjustable, Charcoal Grill from Pitmaker.com
7.) 22" Weber Kettle with Slow-N-Sear
8.) Vault insulated reverse-flow cabinet smoker from Pitmaker
9.) BarbecueFiretruck...under development
10.) 26 foot BBQ Vending Trailer equipped with HUGE Myron Mixon 72xc smoker is HERE, Oct 2016!
11.) Opened www.PaulsRibShackBarbecue.com Food Trailer officially in March 2017
12.) Austin Smoke Works 500 Gallon Propane Tank Offset Smoker, named "Lucille" as travel pit for PaulsRibShack, Oct 2018.
12.) Opening Brick & Mortar location at 4800 Nelson Rd, Spring 2019. Had a pair of 1,000 Gallon Austin Smoke Works pits, both in RibShackRed for our new place!
Fabulous Backlit Thermapens, several Maverick Remote Thermometers (don't use any remotes anymore), Thermoworks Smoke, Other Thermoworks toys, Vacuum sealer, lots and lots of equipment...
I'm loving using BBQ to make friends and build connections.
I have #theRibList where I keep a list of new and old friends and whenever I'm cooking, I make 1 to 20 extra and share the joy.
Mineral wool is all you need. Much cheaper and lighter. I made my cabinet smokers out of 2x4" box and 16 guage sheetmetal with insulation. Can hold your hand on the outside of the pit.
