In what situations have you used 4L/4Low?

[Scarey]

With my 02’ Tahoe, the only way to pull a heavy ski boat out of the lake from basically a very steep dirt road that went into the water was 4L. I would spin otherwise.
I have a question, on my 24’ 6.2 with 4 high and low, are the differentials locked in 4 low and limited slip in 4high?

You have to see which version differential your truck came with. The fronts are open. The rear can be a traditional G80 or an electric locker, I forget the RPO.
