Congrats on your decision.
I'm no Michelin fan, but I've got 8 to replace next month and after shopping like crazy and listening to all the talk I'll probably go back to the Michelin (now X Line Energy Z). Toyos are about $1,000 cheaper and were definately my #2 choice, but they are not the exact size for my coach.
PS - I was carrying the FMCA published discount rate in my left pocket in both Michelin Commercial Tire Stores I shopped at, and walked out with quotes over $20 cheaper per tire than FMCA in my right pocket. The FMCA discount really varies by tire.
