I almost put my truck into one of the ponds behind Water World once, and that was just with an LSD in the rear and a muddy dirt road that was only slightly off camber. If it weren't for the front axle anchoring me, I would have ended up in the pond. Is your rear locker selectable?

EDIT: Let me clarify. I would actually be less worried about having a locked front on a capable trail rig, that is on a trail; and more so on driving in slick conditions on the roads. A lunchbox or LSD on the rear only is pretty manageable on the streets in the snow, but I'd be VERY hesitant to drive with the front locked in the snow, if the rear was also locked. I just recently did a TON of reading on this because Aussie makes a front locker for IFS set-ups as well. There is a guy over in Grand Junction with an Aussie on both axles, he says he does not drive his truck in slick conditions on the roads.

On the other hand, here is a video of an XJ with an Aussie on the front and LSD in the rear to encourage you.
I run a Lock Right in the rear and open front. That covers most of the hard trails in CO and UT. The extreme trails are a different story. Double Whammy, on Golden Spike, is a good example of when this set-up is less than optimal.

If you are looking for an on/off front locking device, I'd lean toward something like an ARB air locker in the front. For on road use, I wouldn't bother with a front locker. Do you really drive more than 20-30mph in 4wd?

Given a choice, I'd rather have two front tires looking for traction then one unlocked hub (never gone that route). Never been anywhere that I couldn't get through either.

Realistically, how off camber do you plan to be? I've run a lot of trails in CO/UT and can't remember anything too steep. There was one section on Hell's Revenge that tilted the driver over an 80'+ drop off that had me, the driver, leaning right. Traction was not a problem, but I could have pooped diamonds.

Guess the question is "what do you want to run?".
