I don't know the actual smoker. Is it relatively thin walled? That may be the only thing that will be affected by the 30 deg (how long it takes to get to temp). I'm assuming, since it's electric, that you'll be able to get to temp.
Other than that, don't open the door. If you have a thermo with a wire attachment, run that through the door so you don't have to open it (every time you open the door, you'll loose heat and have to recover = more time).
