What are you guys getting that drive the 7.3 4x4 6 speeds getting? looking for some realy data, not best tank ever. Mostly concerned about unloaded highway numbers. Looking for a dually, but a comparison between DRW &SRW would be good. Thinking about getting rid of my Dodge and getting a 7.3. /ubbthreads/images/graemlins/cool.gif BTW, at 70 mph my dodge gets 20.5 on summer fuel!
