I'm in Tucson, my tomatoes are all but done growing. Can I cut them back, will they still produce fruit? What is the best way to have tomatoes a little longer? John

This is exactly what we do. We cut them near to the ground but being careful to leave some lower leaves present. The tomato pretty soon starts to regrow from the roots and before you know it, the cage is filled once more. We frequently get a fall harvest this way.
