Having my van down for 10 days recently gave me the opportunity to consider alternatives-specifically the 2013 E150. Used to be the 150 was light duty but I guess that changed @ 2010 or so. Actual payload & towing capacity is not that much less than the 250, same motor,tranny,wheels,etc. Frankly, I'm unclear where the actual difference lies other than the suspension. Any experiences good or bad?
