Diesel. Just going to say it. Diesel engines have plenty of torque for pulling, have better than gasoline burn rates (offset if diesel per gallon price is higher than regular unleaded), and the new diesels are as quiet and "green" as some hybrids with the ultra-low sulfur diesel fuel sold now. I have a Mercedes diesel SUV (yes, it's expensive, but it's my daily driver and I have to have my toys!) which gets the rated 21 city/27 highway all he time; 19 mpg when towing my 6x10.
Unfortunately the cheapest diesel PU is a Ford F250 at roughly $10K more base price (according to my look through Edmunds.)
In the Ford Ranger group starting at $15K, if you are in doubt about pulling performance, go for the six-cylinder engine. You're making the right considerations, but the extra fuel a 6-cyl burns will be justified when towing, and won't make a big difference to your daily driving.
