Re: 2005 2wd SMB Camper V10
Pretty sure all the vans of this age will be limited slip. It helps, but not so you'd notice. Basically if only one rear wheel is on ice, or a similarly slick material in an open diff you will not go anywhere, with limited slip you can actually proceed. So if both tires are on somewhat slick surfaces, its stands to reason it would help, and it probably does but there are so many other factors it's hard to point to limited slip and say "that's why I wasn't stuck". For example, the vehicle weight and tires will have a lot more effect on your rainy road drive. You've more than likely driven or owned a vehicle with limited slip these days.
Regardless it's not really a pro or con, you can just think of it as 2wd.
