This is one of the reasons I don't use the tray and use the AMNTS(tube) instead.Check out the link in my signature,3rd pic.No need for excess foil and tents,simplicity at its best.
That's fine if you can get the Tube to put out less than too much smoke.
My AMNPS works perfectly with it on my bottom rack. (Gen #2.5)
No matter what I do with a Tube, I get much too much smoke from it.
Been using Amazing Smokers for 9 years.
