I am wanting to upgrade from my F150 to a diesel. I have found an 05 SWB F350 4x4 XLT for $15,000. I know the truck and it's been taken care of. It has the EGR delete, all new injectors, superchips programmer and I am 90% sure new head studs. It has 160,000 miles, 5 speed, extended cab long bed. Tires have 500 miles on them. I pull a Travel trailer at around 7,000 lbs loaded up, 2040 john deere tractor and sometimes a bobcat. Sound like a decent deal? I am a little nervous about the 6.0 to be honest.
