I'm the "same boat". (literally). We have a 2015, 20 foot Harris pontoon with a 90 hp 4 stroke Yamaha and hope the Mav, xlt, tow, fx4 can pull it to (10 mile round trip which has 4 to 5, 20 to 40 foot hills to go up and down) and up the ramp about 12 to 15 times a year with no problems. I think the whole package weighs under 3500 lbs. And only the driver will be allowed to sit in the truck when it's being pulled up the boat rampYes the cost, lousy gas mileage and a timing belt is a turn off to me. Others have said what's the big deal replace the timing belt when it's due. I think it is a big deal. I have a 20 foot pontoon boat but ordered the 4k tow. Was wondering if the Hybrid could handle it especially at the launch ramp being fwd and all the weight on the back.
