When locating the drain line for a single bowl kitchen sink that will receive a garbage disposal, should the drain line be offset (in lieu of centered between the hot and cold stub outs) to allow for enough room between the trap and the disposal? If it should be offset, what is the recommended offset?

Mine comes out about centered on the bowl with the disposal serving the right hand bowl. Line comes out and 45's to the left hand bowl trap. Disposal dumps into the left hand trap. I had no problems when I switched to a deeper undermount and had to reconfigure a bit.

You can go with an 8" offset for the single bowl.
The drain is lower then the water supplies.
I would center the water supplies.
And don't forget the hammer arrestor on the hot side.

drain and hammers
We have not used them here in the 37 years I have lived here. The drain off to the side makes an easier installation. Between the radius of the disposer, the elbow drain for it, and the trap's built in offset, you can probably go up to 9" off center, but probably do not need that much.
