I have a 2003 F350 V10, and love it. Mileage is 12-14 not towing and 11-12 towing. Except for very steep hills, the V10 doesn't seem to notice the 11,000# 5er behind it. On the hills, I just downshift, and up we go. I think you will be pleased with the F250. It should definitely improve your safety and handling over the 1/2 ton. JMHO
