Interesting that you mention a limited slip/locker for 2WD Class C rear differentials.
I've for years as much as possible made sure that I had limited slip differentials on all of our vehicles - even our 2WD daily driver 2002 sedan has an electrically engaged limited slip differential!
HOWEVER, our E450 Class C RV has only a standard differential ... I even crawled underneath and wrote down the data from the metal tag on the differential to cross-check and see if "maybe by pure luck" it was a limited slip one. I sure wish it had come from Ford with limited slip. :(
FWIW ... in marginal traction situations you can get a standard differential to act in a limited slip manner by driving slowly with the emergency brake engaged. The brake drag forces the differential to drive both rear axles regardless of which tire has more or less traction than the other one. It works well - once you get the hang of balancing how much gas pedal versus how much emergency brake!
