Elkmont Gas Mileage with '06 Tundra

I think this is probably worse case since we were driving into a nasty head wind coming west across Kansas, I figured gas at $3.90 per gallon.

- I would estimate that the Elkmont dropped MPG by approx 2 mpg compared to towing a TM2619
- Compared to NOT towing anything, the Tundra used 3.3 more gallons per 100 miles towing the Elkmont.
- The Tundra got 17 mpg at 75 mph and 19.8 mpg at 63 mph, towing nothing.
- I averaged 11.1 mpg over 665 miles towing the Elkmont. The worse I got was 9.8 and the best was 12.2 mpg. It would be rare to hit 14 mpg towing the 2619 TM. On a trip to Oregon, we averaged 13 mpg with the 2619, but I was able to maintain higher speeds.

I'd be interested in how that compares to other trucks? The Tundra is very comfortable for long trips, but I think the 4.7L engine is a bit small and underpowered for the truck. It works a bit hard at times.
