Yea, that 8.2 grossing 70,000 would be a power house. I'm running a 400 horse m11 right now, just looking to build a longer truck to handle a pintle hitch better. I've got a 13 foot bed on the truck right now just looking to go to a 15 or 16 foot bed and a third drop axle. The short truck works great, just doesn't turn real well with the pintle loaded heavy.
