4.6 V8 and 4wd, what is your MPG???

Just kind of curious about this, I know I didn't buy this rig for fuel economy, but its a 2011 4wd, 4.6 V8, SR5 with the stock steel wheels/tire combo. I've been averaging 15mpg, which is a mix of 50 city/50 highway in my normal driving habits.

Just kind of curious as to the mpg those with the 4.6/4wd/double cab have been getting.

FYI my previous daily driver was a 1992 Lexus SC300 5 speed manual(yes that was a factory option). That thing did like 18mpg on average, maybe 22 on straight interstate when I averaged 75-80mph. It used 93 premium which is like 50 to 80 cents more a gallon than 87 regular which my truck uses, I did the math, the truck at 15mpg on regular is actually a bit more economical.

 

I do about 100 miles a day for work mixed use... 60% freeway
consistently average mid 18's to mid 19's...... trips high 20's to mid 21's
not too bad for a full size work truck, our hilly terrain & sucky Seattle area traffic

stock '14 SR5.. 4.6 4x4, headache rack, cross bed toolbox & home built truck bed drawers loaded with tools & const. supplies.
I looked at the commercially built drawers, (so much wasted space) said to myself.. I can do better for a fraction of the cost. Used skate board bearings & square tubing for drawer slides.. I can slide them out with my pinky. I used roll on bed coating on the top.. the drawers are 100% waterproof

 

Been sitting at 15 MPG for the longest.

 

Well to be truthful its more like 13.5-14mpg if I drive it like I hate it, 15mpg if I drive easy. Personally this is a big rig without a shit-ton of power, I really don't mind doing the speed limit, looking WAY ahead, trying to avoid slamming on the brakes, granted open road interstate, I'm doing 75-80mph. Still this rig doesn't feel under-powered, yes a bit light on low end torque, but floor it and there is a good bit of power up top. Its a lot faster than my old 2004 Tacoma, 2.4/5 Speed, that thing was a dog.
