Hey guys! New to the forum. So much good info here. Any way I'm in the planning stages of starting my first smoker build. I will be constructing the interior with 1/8" aluminum with the dimensions of about 2 ft X 2 ft X 7 ft. I am gonna insulate that with 2" mineral wool with a plywood exterior. Any problems with this? Also i was planning on putting two air vents, one in the front one in the back. Then 2 exhaust vents, one on each side. Is this a good idea? I have seen some builds on here with just floor vents for exhaust and some that have stacks. Does it matter? Where do I put the exhaust vents? Some are on top some are coming from the sides near the top. How big? Any advice would be greatly appreciated!
