I have looked at the charts and read many threads on this, but it seems like logistics may play a part in the choice of gearing and 37`s? I live in Minnesota and have a 2013 JKUR and am installing the lift and KO2 37`s hopefully this weekend if the lift opens up. I drive some freeway and pull a small 2000 lb trailer on occasion. Between 4:88 and 5:13, what would be a better choice? I don`t ever plan on going bigger, and I would like good drivabilty and if it is possible 15mpg range.
