yeah, i think you can do an 8-9k lb enclosed with the 6.0. i know a guy who hauls his AS with one and loves it. says he gets 9mpg hauling though. 14 around town.

iirc the 6.0 is like 330hp and 370ft/lbs. our 5.3 has 315ft/lbs, the new ones have 330. i've been shopping trucks a little lately, and i think my ideal setup is a 1500 6.0 hauling a 20 or 22' aluminum V nose.

i don't think i like the V10. i pulled a 24' unloaded enclosed with a F350 from Des Moines to KC once and i wasn't impressed. Another friend has been through at least 1, but i think 2 motors under warranty in his F250. I think there's a certain run of PSD's that are good, but if you're going gas, i think the GM stuff is where it's at.
