i have to disagree with the person who said only the tundra can tow at it maxed out rating, i think any new truck with tow/haul can tow its max, here is my load
boat- 5000 pound dry weight (the dry weight is just the hull with nothing else added but the engine) , add 75 gallons of fuel, a c5.7 260 hp v8 (made by gm btw), seats for 7, equipment, 3 batterys, 30 gallon fresh water tank, 25 gallon waste tank ( only full on the ride home) hard top on boat adds about 400 poinds, and just the little stuff like cabin creature comforts, not sure how much a corian counter top weighs, or a microwave.
so added up with 6 200 pound guys and coolers and a fishing rod holder on the grill
5000 lb + 600 pounds of fuel + 240 pounds of water + 200 pounds of waste+ what ever fish we cetch (usally what we pick up at the store because we goof off more than fish), coolers are about 100 poinds total with ice, soda and water, fishing rods are probably 50 pounds with all of them and tacle and weights,
so that equals to an guesstimated ( i round high just to be safe)
about 6700 pounds, when i have tow haul mode it drives great, sure i notice a preformace change but any truck would when towing, i have plenty of passing power, and i can drive for ever like this, me and some buddys went to west virginia for a weekend to fish on the lakes, i had no trouble with the grades, i needed about half throttle to get up a 7 % grade, and i down shift to 2 when going down a hill. this thing is a towing monster. :Chevy: :Chevy: :Chevy:
