Thanks Joe.
cfelton,
Our truck has the 4.6 and it did the tow without issue. However it did pull hard in the mountains. The 5.7 will tow the V with easy. You are correct about the gas mileage. We got about 9 mpg towing. We could only get 200 miles out of a tank before the fuel light would come on. Before I bought the truck I did some research on the toyota/lexus V8 and there are some reports of the engines going 750k before rebuild. I'm sure they were fleet vehicles and I can't prove anything I read online. Good luck with your new Tundra.
