Myth: Lifting the front wheels off the ground with the leveling jacks will damage the suspension.. (Can not tell you how many times I have heard this. I have the qualifications to say BUNK it's a myth.. This suspension is designed to hold up thousands of pounds of motor home. a couple hundred pounds of "Traction" (holding up the wheels and axle) won't hurt it one bit)
Fact: With BOTH front wheels off the ground there is a danger if you get hit with a strong side wind, It can pretzel the jacks and at 400-600 each plus installation. that's one (Well 2 and possibly more) Very expensive pretzles.
Now my situtation.. My jacks don't jack.. So I carry a car full of 2x12.
