My Sprinter based RV is more stable in cross winds than my E350 based Chinook ever was. I suspect the Ford front suspension (which has massive amounts of bump steer) has a hand in this. My Ford used to dance all over in cross wind gusts. My brother's E450 does too. I feel a big slam in the side but the truck is rock stable. I've driven in constant cross wind for over an hour when I had to crank in a whole bunch of wheel just to maintain heading. She was dead stable although I suspect it wasn't so good for tire wear. Overall the only issue is the Sprinter "driveway rock" and that's largely due to lack of damping. I probably will get stiffer rear shocks some time but it's not really an issue for me. Underdamped is underdamped whether you have a wide track or narrow.
Dakzuki,
I don't doubt you at all. As I mentioned earlier, you as do many later model Sprinter owners have the same story.
For us with our previous generation 2007 E350-V10, we were able to achieve excellent handling under the worst of conditions, but it took significant suspension improvements at a cost of $3900. The latest Ford chassis design has addressed some of the previous generation deficiencies, but not every deficiency. Some Ford owners today may still have to dish out a little extra to compare to the Sprinter. It depends on the configuration of house and weight distribution. With such improvements and the wider stance, the E-series translates to excellent slaloming on mountain & canyon roads. I speak from personal experience with our upgraded 2007 chassis. I have to be careful not to take the turns too hard only for the reason of the items in the cabinetry and fridge. Otherwise, I'd be in competition mode :)
I feel the serious Ford-versus-Sprinter debate is unrelated to the rear axle stance. But this discussion is focused on the stance.
