I don't tow with my C10 and specifically wanted to cruise, so I can't answer that. If you plan on towing often then a gear swap may be what you need. I suggest installing the 700R4 and see if the 3.08s can handle it for occasional towing - if not, then you can swap to the 3.73s.

Here's a link to a Q-jet/700R4 thread...you may want to Google some others.
