I don't want this to turn into a gas vs. diesel thread. That is not what i am after, I looking for more thoughts on what would be better.
I currently have an 01 F250 w/v10 supercab short box. I love the V10,but hate the mileage of towing. The best I have gotten towing is 10, the worst is 6. I tow around 10k with an 18ft trailer. I am looking at a 28-32' gooseneck. I am thinking of going to a 7.3ltr diesel, just to have the power their to handle the load, and hope to have better mileage. I tow roughly 5-6 times a year doing a minimum of 200 miles one way. With a few bigger trips planned this coming year. So far while looking my payments would go up $75, depending on trade value. I put 12,000 miles on the truck in 2 years. Mainly because 9mpg driving in town is not fun to think about. please help with insight.
