I went to the Traeger web site and found no information on the materials but that is no big deal.
What I did like was the thermostat control that had a wide range even though it didn't get down to 120 F or so.

A friend of mine has one and loves it.
I have no idea what brand it is.
On a side not they have, 'or at least I have read they have, tried to get these type smokers disqualified at cook offs because they are so easy.
Give me a frigging break, step up to the plate and get better losers.
Reminds me of the Hemi ban NASCAR had because the losers were crying they couldn't out run them.
Cry me a river.
