Has anyone out there had any experience in towing heavy boats with a V6 4Runner (2003)? I'm looking at buying a 2005 X-Star (4250 pounds dry) with tandem trailer (1250 pounds). The towing capacity of the 4Runner is 5300 without the towing package and 6700 with (we're not sure if my girlfriend's truck has it or not). Regardless, if it does, the only change is a new top end gear and an AT cooler.
I currently tow a 1996 Tige 2150 (~2850 dry) with single axle trailer (~750). I haven't had any problems towing that boat or pulling it out of the water with 4 or 5 people in it.
I normally keep my boat at the lake in dry storage and tow it less than a mile total for gas and launching - the launch ramp is shallow with very little slope and no moss - highly textured concrete.
BTW, the truck has factory tires and has somewhere around 260 hp and 283 ft/torque.
What do you think? Would it work? My biggest concern is having her truck get dragged into the lake.
She would be seriously pissed.
