Bought a pre owned '16 xd 5.0 to haul 7500 lb rv. Absolutely love this truck. Have taken multiple trips w/ rv, proper pre trips and soforth. Last trip went to Ozarks in Ar. Pulled GREAT, no problems at all. Got home, took trlr in for svc. All is well. Trlr fixed, on way back to house, truck just felt and sounded different. No dash warnings or lights. Paying attn to overall feel, and then.....dashboard Christmas tree! Lost pwr, truck died as I'm shouldering the whole rig. Threw a code for crankshaft position sensor. Towed in, changed sensor, No Joy. Diagnosis says busted crank. Read some other horror stories about this issue. Now scared to death that 5.0 not a good motor, and its not being made any more. Any thoughts?
