You're KJ is as custom or personal as you want it to be. What do YOU want to do with it would be the best question to ask.....being in Colorado, I would hope hitting the trails
If so....most importantly, protect your undercarriage with skid plates and rock rails, and get some tow points for when you get stuck or hung up on something....happens quite a bit....other than that, other things will come as you see you'll need it (lift, tires, etc..) but to start out its best to protect your rig from damage while you learn the ins and outs of off-highway driving.
By the way.....love the color!
Have fun!
