I'm new here, but I highly suggest a 1987-1996 F-150/F-250/F-350.
Standard cab, long bed (Or flat bed, your choice) and the lowly 4.9l I6. They don't rev as high as a 302/351 v8; But that's the beauty in them. Paired with 4.10 gears and the old 4 speed (Or if it's F250+, the ZF 5 speed) it'll pull Hell off its' hinges; And not break a sweat.
MANY MANY MANY I6's reach 200,000+ miles before needing anything more than a Waterpump, or a good tuneup.
The 8th/9th gen F-Series trucks are extremely cheap...$500-2,500 for a running truck that is extremely reliable.
My 1992 F-150 (Standard cab/ longbed) with the 4.9l/ 5 speed averages 17mpg mixed, and is PAID OFF.
