Thats why I own a 4x4 in both of my trucks. If your like me, I don't get to the ramp until late, and the ramp is always slick when pulling my jet boat out. If I didn't have 4x4, I would be telling a story about how I slid back in to the water. You should be confident with your set-up, that it will pull the boat out and drive home safe. Happy boating and 4x4'ing.
