2015 Toyota Tundra Double Cab SR5 4dr Double Cab 4WD SB (4.6L 8cyl 6A)
"The Under Dog"  4.6 is a great truck
 I bought 4.6 double sr5 4x4 almost 2 years ago. Overall performance of the 4.6 is great for myself as I don't do a lot of pulling. I use the truck for lumber,hunting,sports activities for my children, it's my everyday driver. Currently have 34,000 miles on the truck. No issues with anything as it shouldn't for its age. Over all impression, great value paid around 32k for it new, didn't think I could touch a Toyota at that. Checked out 2017 they range around 34k. That's a reasonable price as far as I'm concerned. Like the review camera. Like the over size touch screen for the radio. Love the front center fold down console/seat. If you ever need to haul a six person. Gas mileage in the summer if you drive it around 65 to 70 mph you'll get 18-19 mpg. Winter same speed around 16-17 mpg depending on how cold it is. Only thing I don't like is the cheap looking gray steel wheels and the bed of the truck seems a little light weight. Had it out in some snow and ice didn't miss a beat. Like that the truck comes with some really good Michelin tires. The engine warms up quick in the winter cause it's aluminum so that's a plus. Toyota care two yr , 25k mile free maintenance great. Like the truck has 10k oil changes less time and money later out of my pocket. Like that I have storage compartment under the back seat, lots of space under there. Over a great truck for me
