yep, what everybody said. specialy the tranny cooler. if ur truck dont have one (prob not) it would be a good investment. specialy in the hills. if you gonna be towing the boat for the next few years, you'll be glad it there. if it were me, and i didn't have the funds for a cooler, i still wouldn't hesitate. just watch ur guages. if she starts runnin hot (motor) just pull over and let her cool. heat will make a tranny slip, thats ur biggest worry. with or without the cooler, do NOT pull that boat home in overdrive! whenever towing anything leave ur tranny in third. never overdrive.
