The E350 has the same chassis as the 14,050 GVWR E450 (which would be the outgoing 6.2L engine option). The 14,500 version does have a heavier frame. And a larger rear axle. If you regularly run at over 20,000 combined, you will want the E450 and it's heavier rear axle. But other than that, it really is just a difference in spring rates.
