I put a set of M/S 2's on my F-150 and put 30,000 miles on them most of that towing a 22' 5K# TT. The ride and handling was outstanding. After trading up to our 2012 Class C, on a 2011 E-350 chassis, I got the recall notice for the M/S's that it came with. The original M/S were a 20 year old design and they were seeing some tread separation issues.
The tires only had 16,000 miles and looked fine but since Michelin was buying I was happy to upgrade. Got six brand new M/S 2's ($1,500), mounted and balanced for free... one month before a 7,500 mile cross country trip. :B
The potholes back east gave them a serious workout but as with my truck the performance is awesome. There are lots of fine tires out there but not many companies would stand up like Michelin and back their products. Like they say.... There's Michelin and then there's everything else.
