I am in the process of designing a camper for a Dodge 5500. The 5500 has brand new axles that have ratings of 7000 lbs front and 13,500 lbs rear. Since my gross weight will be around 12,000 lbs I figure it should be a pretty reliable package. My dilemma is no one makes any lockers for these axles. Dodge offers a rear limited slip as an option.

So here is my crazy idea. I have read on other 4x4 forums of rock crawlers using line locks on the individual brakes. The idea is when a tire spins/ is airborne, lock that brake and the other side gets driven through the diff. This also is convenient for making very tight turns, which may be very convenient on a large truck. The turn is done by locking the inside rear and then when you apply power the truck pivots about the locked rear tire.

So will this work on a vehicle designed for more "expedition" type use? I figure the wheel brake feature will help me since without lockers I am more liable to get stuck.

I plan to order the truck soon and I need to decide whether or not to get the limited slip diff. I expect you can not use the wheel brake feature with the LSD since the LSD will be fighting you if one wheel is locked.

Any comments appreciated.
