About 10 years ago, a friend of mine needed to slide a shed away from a lake’s increasing waterline. I tried to use my 4×4 Jeep Wrangler, but it couldn’t do the job. An hour later another friend showed up with a Ford Excursion and pulled it without a problem. All of my friends are engineers and said. “Well, it’s because we needed a longer wheelbase”. Why does that matter? Isn’t it about mass?

The longer wheelbase added some downward torque (force) to the front of the vehicle so the back wheels would move in a more forward direction. The short wheelbase of a jeep will slightly lift the front of the jeep and give the back wheels less weight to support good traction (think of a wheelie). Honesty, you could have sat a couple of heavy weights on the hood and done the same thing (I’m guessing). Or just get a winch 🙂
