“Bought an F-150 STX 3.5 DT, love it”

So far, so good.

A dual turbo, electronic controlled 3.5l works GREAT at 4,000 ft. of altitude.

Without a headwind it even gets decent F.E.

I just traveled from PA to TX with my toe-behind camper, gross wt about 9.5k, averaged 11-12 mpg the whole way down here - I think it does all right.
