I too would suggest Toyo over Michelin. I also do not agree with the notion that commercial tires from Japanese companies have a harsher ride and especially the cockamamie reason whoever it was who gave it to you.
Like others here on the forum, I actually found the Toyos had a smoother ride and better handling than the OEM Michelins they replaced ...and for a lot less money.
But if you're a diehard "Michelin man," I can't fault that but as I've said in dozens of posts here over the years, my personal opinion is that Michelins are good tires but way over-rated and there are better choices pertaining to value. I've heard some on the forum state "I buy Michelins because I don't want to put my family at risk." It actually makes me chuckle when I hear that. For me, Michelins are not necessarily safer or have less tendency to fail than any other brands that are well-known. It's not that I think that Michelins are bad (although they have had problems with their RV-marketed tires in the past) but it's paying more for a product when you can purchase a comparable product for less money. Much of what you pay for a first-tier tire such as Michelin come from just that ...their so-called premium reputation and making your "donation" for all their advertising costs, etc. I'm a fan of the tires coming from the Japanese companies ...Toyo, Sumitomo, Yokohama, etc.
Pertaining to having tires delivered for installtion to a company that sells the same brand, what I've found in the past is that more often than not, they will essentially match or come close to the price you're paying from wherever you're getting them from.
Sure, they may not refused to accept them but they may charge you premium prices for installation and related expenses. If you buy from them, you will more than likely get a better price. So in the wash, ordering from somebody else and having them install may not save you that much when calculating the final price.
I'd call a company like Callaghan to see if they'll match or come close to matching the price you are finding online and see if you can negotiate a package price from them for the tires and installation.
Callaghan is a factory authorized dealer for both Michelin and Toyo (along with a lot of other brands too) so talking with them first might give you a better idea for availability and the freshness of tires they are able to secure. They have a location in Fort Meyers that specializes in commercial truck tires (actually, their entire business at all locations mostly specializes in fleet servicing and trucks):
