Ok, I payed a little more attention tonight on my way home. I made sure to keep the cruise set to 65 the entire way home.
It's a 2003 7.3L Crew Cab Fx4 with 305/75/R16 Cooper Discovery tires. I know the stock tires are 265's, and I believe the 305 is pretty much a 33" tire. After 111 miles I stopped and was getting 10.4mpg. I'll try to post some pictures tomorrow so yall can see what I'm dealin with.
