1500HD & 31' Excella
Nothing earth shattering here but I'm pretty happy so...
Took the kids to MS over spring break last week. Round trip was right at 900 miles. We just refueled the truck today, and averaged 12.25 mpg for the trip :-) All but about 50 of this was towing. Best fuel economy was
on the way back, warm temperatures, nice tailwind (13.6). Worst was the leg that included part of the Natchez Trace: (10.2), probably a combination of a fairly stiff headwind and a pump that didn't shut off right away. Could also have been some of the traffic around Nashville.
Needless to say, we're pleased.
What's funny is that the best we've ever seen with this truck - without the trailer - is around 14.5. Go figure.
Details... 2003, 6.0 liter, 4x4, 3.73. 2 adults/2 kids plus a bed full of bikes & such.
