I've been doing this since I first bought my first MES 30 this past Nov.Makes using the tubes a little more convenient and easier to handle.Fits great in my MES(pic3) or anywhere there's more a less a level surface and limited room.
More than one person has asked me why pitched(pic2)?Keeps the pellets from falling out and you get a slower more consistent burn rate,which would explain why I'm getting close to 3hrs out of a 6" tube (over six on the 12") and not as intense smoke as many others have reported with the tube(s).The 12" tube almost guarantees opening the door only once on a long smoke and the bolt in the back can be shortened or eliminated altogether on the 12" tube to achieve the proper angle though I still like to have the back ever so slightly elevated for ease of use.Opening the door and replacing the tube with a fresh one and closing the door takes less than 10 seconds,heat loss is minimal.
The tube inherently puts out more smoke than the tray so you need to take that into consideration when it comes to duration of smoke.I would also suggest checking out this thread that
chopsaw started regarding using crushed pellets in the tube,you will get even longer smoke times and less smoke.

The
AMNTS with this mod is a great option if the tray isn't working for you,especially when using crushed pellets.The tubes work awesome on hot/humid and windless days too.
This mod works just fine with the newer oval tubes.
