Wow, don't know now if I should sell and get something else or take a gamble of getting some miles out of it. I've read many conflicting stories on 4.7 engines over the last couple days and it sure seems a 50/50 deal to make the 150k mile mark. Truck sure is a nice driver, very comfy and quiet but only gets about 11.5 mpg city driving. I guess that might be impacted from the AWD system ? is the AWD 4x4 drivetrain problematic also ? Have 2018 ford RCSB I'm installing whipple on and bought Dakota for work rig, hum....have to check into what remanufactured engines go for a worse case..... Thanks all for input
