This isn't true, espically on a vehicle like a suburban. You have the rear springs, axle, drive shaft, gas tank, etc all in the rear, transmission and transfer case in the middle and up front is an aluminum cased axle, engine, etc. The weitgh is pretty evenly spread out, CG is pretty well centered.
