Because of all the gravel we will encounter on the Alaska Highway, I put Humvee rock guards on both headlights to protect them from flying rock.
I got tired of coiling and uncoiling my extension cord each day to charge the batteries, so I mounted a wire reel on the bumper to roll the cord on. Works Great!
Being an arctic jeep, it's got to have some heat. I converted a ceramic space heater into my jeep heater. It works well.
