Oh I can answer that.
2000 7.3l excursion. Average about 9.5 mpg towing 10k pound travel trailer averaging about 60 mph. As low as 7.5. As high as 12 (but only once)
2001 7.3l f350 dually. Average about 8 mpg towing 15k pound fifth wheel toy hauler about 60 mph. As low as 6.5 in the mountains and as high as 9 (but 9 is probably a lie.)
