Tundra 5.7 Owners
What gas mileage are you getting towing and how much weight are you pulling?
Forum Discussion
I have a 2007 5.7L CrewMax pulling a 2013 Crossroads Z-1 (~4800lbs). I have about 200lbs of stuff in the back of the truck. This is a recent (August) acquisition with 4 trips in it so I don't have the best set of data with it but I will give my experience.
As others have said, speed, wind resistance and consistency are what makes or breaks you on mpg. I used to have a Rockwood popup that matched, height and width wise, almost perfectly with the bed of the truck. It was just like adding another 12-14 feet to the bed. Pulling that at 65-70 I could get about 12-13. Since getting the travel trailer I have had to change the driving habits :).
The worst I have seen is 7.8 and that was just about the worst possible conditions. Stop and start traffic, hills, into the wind, raining. Just bad.
Using S-mode, staying below 65 and staying out of passing gear helps the most. I don't have enough Tow Mode tests to know if that impacts all that much. Best I have seen so far has been 9.9. It dropped just below 10 about 30 minutes from home. On that trip I was keeping it right at 65. Now there were times to pass I had to go above 65 for short distances. If I were to lock onto 60 I could probably get 10-11 easy.
Basically its a tradeoff, you go slower and you get better gas mileage. My Tundra, she doesn't like slow ;)
