Yeah ... that's the next best thing to have next to 6X4. ;)
I sure wish our E450 Class C had a limited slip rear differential so all four rear tires were driven when I need it most.
I doubt it would even be available, in speaking with driveline shops over the years they’ve all said the same thing, putting a locking diff. on anything heavy is a waste of time. The first time it engages under load is the LAST time it engages.
Even with a careful driver, all it takes is a little slip say pulling off the shoulder and back on to the road and you have a high torque high speed lock up that hand grenades the locker.
As you say though, with all that weight you maxed out your potential traction as it is.
