Just remember that there’s relatively little smoke at high temps. You’ll get the most smoke at low temps. Despite what you might read about smoke production, I think the 590 does a great job.
Speaking of great info. RT never has the folding front shelf for the Stampede available, and I was never overly impressed with the design. Thanks to others on this forum I just ordered 14" stainless folding brackets off of Amazon and will be building my own wood shelf in the very near future!
