IMHO...
If you can afford it, GET IT!!!!!! Do you need it, no. The day you do need it and think back to "I don't need it", you're going to kick yourself. You gotta think that when we do get hit with rains, the few trails/dirt roads get some good size washouts due to flash flooding and 2X sometimes won't let you get through it (Plus getting stuck in the mud w/ 2x sucks). Has happened to me 4 times in 4 years... so the question is, can you live with the fact of potentially limiting your hunting locations in the event of something like this? Other than that, the roads through most of the NF's are pretty mellow. Buddy of mine has the exact same truck as mine but with 4X and he can climb MUCH steeper terrain, I even have AT's and he had stock tires.
