I came from a 98 24v and can say after 5+ years the difference in fuel mileage between the two is minimal. Towing the 14 does better in terms of efficiency. Power and comfort there is no comparison.
If you must idle due to the temps make sure to engage the high idle. Install that winter front. Plug in 1-2 hours prior to starting whenever possible even if in a garage, unless it is heated. A timer makes this task much more efficient vs plugging in all night or several hrs at a time. Electricity is cheaper than fuel!
