Caver Dave, I have owned or driven every 1/2 and 3/4 ton truck made over the last 6 years and my Tundra is by far my favorite truck. My commute is 45 miles each way and I average 15-16 mpg, which is normal for most trucks. On the highway I avg. close to 18 mpgs. The towing mileage isn't great, with my open trailer loaded at about 10,500 lbs. I avg. around 8 mpg to Harlan and back from Clayton NC. With the enclosed trailer at around 11,000 lbs. it dropped to around 6.5 mpg. Now that's through the mountains at 70-75 mph. I have gotten 10-11 mpg when towing on mostly flat grades. Overall the Tundra makes a great dual purpose rig because it is fun and comfortable to drive everyday, and has plenty of power to tow just about anything you could want. Don't be scared at all to get one. vehicles owned 99chevy 1500, 2004 nissan titan, 2006 dorge ram hemi. vehicles used at work, 2006 duramax, 2008 duramax, 2006 ford f150, 2006 gmc 1500. The diesels will get better towing mpgs, but to me they aren't as fun or comfortable to drive everyday. Hope this helps
