I built a K5 because that is what I like but I'm a fan of the Yota's !
Pound for pound the Yota's are tuff as nails and with a few exceptions are very well built compared to what else was offered.
Given the same tires and lift on each rig, with all else bone stock ( as in just how it came off the showroom floor ) , I think a FJ80 is just about the best set up ever offered. The Jeep Rubicon deserves honorable mentions but it is my opinion that it would fall apart long before the Yota needed its first U-joint replaced. Just my opinion......
