We have the MS2 on our 07 Roadtrek 190P and find them to be very good for us, handling very well, but we also have significant suspension upgrades that make the van extraordinarily stable. We are good to 85mph+ with no issue. There is no doubt that the MS2 have softer sidewalls, which we like for the softer ride they give compared to the stock Bridegstone Vsteel.
From everything I have read, the Dodges do the best with stiffer sidewalls. Many, many, many folks have found the best tires to be Michelin XPS Ribs, which are much more substantial in sidewall strength, and do a good job of settling down the often very wandery Dodges.
