Diesel efficency vs. rpm discussion

In researcing a jeep diesel swap I have learned alot. I want to move 3500 pounds at 70 mph. To do so with my current gas set up I turn 3000rpm. Now If I was going to use a diesel and want to run it efficently would I gear it for as low an rpm as I could get or does each engine have a ''sweet spot''? Its a 2.8L power stroke made by international. I think it red lines at 4500 rpm. Any insight about this would be of help.
