Vans are great tow rigs. Tow with a GM van myself. I built a high compression 383 with aluminum heads, have it backed to a 4L85E and 3.73 gears. Van itself gets 20-21 mpg on long trips running 70-80 mph and about 12-14 towing my 26' travel trailer at 65 mph. Adding displacement via a stroker crank and airflow via higher flowing aluminum heads both increased torque and horsepower. More power actually helped my fuel economy compared to the weaker 350. The only aero I plan to add is a taller air dam under the front bumper. Beyond that my efficiency and power improvements are the engine, tri-y 4-2-1 headers, free flowing exhaust, upgraded intake, tuning, under drive crank pulley, and synthetics.

Definitely still some low-hanging fruit on that setup, but clearly a fair amount of effort was made.

One day I will live to see the day when side mirrors are not legally required.
