Scary Handling Problem

There's not all that much room for tanks under the front and sides of a Class C till you get behind the wheels. To me, the bigger transgression, more than tanks back there, is not making the wheelbase long enough to put an adequate share of weight on the front axle. Both for handling, and not overloading the rear axle.

You've weighted it, aligned it and stabilized it. We think it's front-light. Let's borrow about 500 pounds of workout weights and load them in the cab or just behind the front seats. See if it's better.
