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 even crawled under it once to check the numbers on the differential to see if I hadn't lucked out with a locker when we bought the motorhome, new, off the dealer's lot ... but no such luck.
I wound up with the usual - only one rear dual set at a time being powered when things get slippery. My only Saving Grace is the tremenduous weight on those two dually sets. Maybe that weight will help force the differential to keep applying torque to both rear axles whenever it can't break either dually set free in moderately slippery situations.
My one big hangup with Class C rigs that have been converted to 6X4 is the raising of the overall height of the motorhome. All six tires driven is the ultimate in traction - but raising the CG of an already tall Class C is not good.
