I love our 6.8L V10 F250. If we ever had to replace it, I'd be looking at an older truck with a V10 in it. Use it primarily for towing and gets little use over the winter.
We have 4.10 gears and it will out-tow just about any other pickup on steep hills. From BC to CA, over to NV and back via UT and ID, got on avg. 8-9 mpg and IIRC, as low as 6 something on a long steep uphill leg and 11 something on a long downhill leg. As high as 6600' elev. so far as well as some steep grades and no lack of power towing a 7K lb TT. MPG really sux on short local trips.
They oughta come out with an eco-boost V10. Make V10s great again. :)
