Doc, serious about a dd? I hate to say it, but the chevy pickups are probably the best way to go.
From my view as a mechanic and comparing jobs between the big 3.
Oil changes, dodge oil filter is above front diff,and spills oil everywhere when you fumble with it. Ford? Above diff also, long arm and proper tool required.
Chev? Bottom of engine,mount is cast into oil pan.
spark plugs? Chevy wins, hands down. Cheap plugs and you can see them. All.
Exhaust manifolds? Bolts and studs break on all 3, gms are easier to get at.
Intake manifolds are by far way easier to get out on the gm engines too.
to each his own but i wouldnt think twice about buying a chevy over a dodge or a ford.
They get decent fuel mileage too.
