chevy, i have a 98 chevy silverado 4x4 Z71 with a 5.7L 350, i've put it through hell and back and still going good, i put it in a mudhole one time where the water came up to the middle of the grille and had water in the cab real close to what you call the transmission hump, i got the truck out of the hole by myself, no winch and nobody pulled me out, worked it out in about 2 or 3 minutes and then drove it 115 minutes home, its also comfortable, i can drive all day with no problem, i've driven 5 hours straight with only stopping once only because i had to get gas after about 4 hours or so, i've also used it to work to hauling and towing and i've had pretty heavy loads before and it didn't even hardly feel it
