i have a 4.6 baby v8. i like the fuel economy. though it'd be nicer with 3.73 or 4.10 gears, the 3.55's make it like 2200rpm at 75mph.
its also a half ton, and a light duty rig. it won't get 4x4, a high top, pop top, on board water, rear ac, roof rack or otherwise, just something to use as a "steel tent" and to haul my moto. will end up insulated, with a simple bed that folds into a bench.
