What To Carry In Your 4x4
and Equipping Your Vehicle

On "Easy" 4WD trips two-wheel drive is usually acceptable with high ground clearance. Four wheel drive (4WD) makes the trip safer and there will be less tire spinning.

"Easy Difficulty" 4WD TRIPS

What you should carry and how your vehicle should be equipped when you leave the safety of the pavement to venture into the backcountry will depend on the difficulty of the trip and, of course, how long you intend to stay. Based on many years of experience I have categorized "What to Carry" and "Equipping Your Vehicle" by trail difficulty. There is no need to carry extra axles on a picnic to a frequently visited campground in your local Forest. This is not meant to be a complete list but rather a place for you to start when you develop your own list.

Four wheel drive vehicles with a rear locker is required. In addition a locker or limited slip in the front differential make the drive safer. Low air pressure, roll bar, off highway experience, and a buddy vehicle are important. Plus: "You can never whimper over body damage." ATVs and motorcycles the "Most Difficult" routes are for experienced ATV & M/C drivers.

Rubicon lockers in high range !


I heard a few guys talking about running rubi lockers in any gear.

Well I did it. It costs a dime and takes 15 Minutes to do. Pull the dash upper trim and take out the 2 screws there. Snap off the center dash panel. Remove the four screws holding the swith panel in place. on early rubicons look for the red wire with white stripe. on the 05 Rubicon look for the violet wire with the orange stripe. Right next to that wire behind the switch is a black wire. bridge the 2 wires with a 10 cent trailer tap splicer. you know the little 3M blue splicers.

Now your locker switch thinks the jeep is in 4 lo all the time.

If you dont think its safe dont do it. I am now able to lock the rear locker in 2 wheel drive when pulling out of the slippery wet boat ramp. I will be able to use the lockers if I feel like it in the snow now also.

I am not questioning the manufacturer for making the switch the way they did. For me this way is preffered. If you dont think its a good idea dont do it.
