That's for the electric (selectable) locker, not a limited slip. When engaged, the locker will lock both rear wheels together with 0 slippage, like a spool. Provides great traction, but poor handling on road (and a lot of other drawbacks). With the ability to disengage the locker, the rear diff is able to slip when turning/cornering, returning normal driving characteristics. A limited slip can allow the rear tires to spin at different speeds for turning/corning, so no need to turn it on & off.

If you don' change gears I'd lock out 6th gear and maybe even 5th with your current gearing.
If the trailer is 7,500 dry, you need a new truck, yours is only rated to tow 8,500 if it is a supercrew.
