I myself actually went from a Tundra to a 2014 4Runner and am so happy I made the switch. I loved that truck and it was very good to me, but I just didn't have a use for a truck anymore and its just the wife and I, no kids. I had a 2007 Tundra Double Cab with the 5.7. That 5.7 is amazing, but seriously be prepared to spend some money on fuel. The dealer told me I would be getting 18mpg or so, not even close. It started out at 15mpg which was a mix of highway and in town, but once I added a leveling kit, 35" BFG KOs, Grill Guard, and a custom made roof rack, it went down to 12mpg. I did have some problems, some minor and some major, but for the most part, it was waayyyyyy better than the Silverado 1500 I had by miles! If you really want one then go for it, but if you don't have a solid reason to have one, I would not go down that road again.
