FYI, next door neighbor owns a Diesel truck repair center, with many years of experience, and he works on all of the brands. He just purchased a 6.2 gas and will not buy any of the late model diesel engines due to the extreme cost of repairs and lack of parts. He says the EPA regulations have eliminated any advantage diesel had over gas and they are only worth it if you have the need for the torque for extreme towing. Just another opinion.
