When i was at the SEMA show this past October, I saw that Ford had developed a full-time front wheel drive F-450. The bed was dropped and the tailgate could be lowered to the ground for use as a ramp. At first I thought this was an inconceivable concept, but
after going to the manufacturer's website www.dallassmithcorp.com (http://www.dallassmithcorp.com), it appears they have this type of suspension on a number of different applications.
