Picked up a 6 x12 U-Haul trailer this morning for a 100 mile run north to pick up some furniture with the whole family aboard along with tools and hand trucks and what not in the truck. At 71 mph she averaged 14.5 mpg on 93 octane @ 0% alcohol content on the way up. On the way back, loaded down with an extra 900 pounds or so, she averaged 13.9 mpg at the same speed. Tires were set to 47 psi cold, they were 52 psi up front and 54 psi for the rears when hot.
The transmission temp at speed got down to 156 with an ambient temp of 82 outside on the trip north and 162 headed back down south. Coming off the highway and entering town on the way up the transmission temp got to 183 in city driving, about 7 miles worth of stop and go along with a steep climb over a bridge to Merritt Island.
The old girl done good!
