Here's my 2 cents worth. My first coach had XRV's and I had 2 zipper blow outs, my second coach had XRV's and I had a blow out. Since I run Michelin on all my other vehicles I put 6 new Michelin's on the coach but put on XZE's and haven't regretted it. With the XZE's I can run lower pressure to carry the same weight which gives a softer ride. Mileage isn't really an issue with RV tires so for me it boils down to what I have the most confidence in and for me it's Michelin. Good luck with your decision.
