I did 6 whole Costco fryers without the beer can a few weeks ago; I could have loaded 4 whole fryers per rack with no problem. With beer can stands, you may be able to get 5 per rack.
Let's see, 5 per rack times 2 means 10 chickens.
Drinking 1/2 can of beer from each mount while carry chicken out to smoker equals 5 beers.
5 beers in the time it takes to get from back door to smoker equals
not being able to find smoker, and really caring at that point.
Just saying!
