temperature variation

[hunter2c]

I am considering purchasing a 3 and have a question about the temperature variations from front to back and bottom rack to top rack? Is there much variation?

Not enough that I care about it.

Hi Hunter, Welcome aboard from N'East MA!
There is some variation from top to bottom due to proximity to the heating element. I have found that placing the larger items closest to the element makes it a non issue.
+1 on Brian's comment especially if you use a probe to monitor internal temperature of the meat.
