Limited slip?
Why do I need a limited slip rear end? I am ordering a new 150, I pull a 4000lb bassboat, I have always used standard rear ends in my G.M. products. Is the limited slip a stronger rear end? Don't they require additional maintenice? I don't want to sound like a rear end, but if I can't get out of something that's why I have 4x4. Somebody sell me a limited slip.

Actually, with an open rear end, you really only have a 2 wheel drive when you engage 4WD. One rear wheel and one front wheel will get power.
The LS rear will give you extra traction in the rear where it's needed the most when pulling a boat up a ramp.
It will also come in handy in low traction conditions, such as another member's experience just the other day. He had to drive uphill on an icy road. He put one side of his truck off the road where there was traction. The LS gave power to the wheel with the traction. If he didn't have LS rear, the tires on the icy side of the truck would just spin and he would have stayed where he was.
It also comes in handy when you're stopped on the side of a road. When you have one rear wheel on the pavement and the other on gravel, you can accelerate a lot faster and you will kick up a lot less gravel with an LS rear.
Sure, it costs more at purchase, but personally, I think it's worth the extra cost. The maintenance difference is that you need to add a friction modifier to the oil. It's not expensive.

And the factory installed one is a fraction of what it costs to be installed in the aftermarket.
