I recently upgraded to a 2007 Monaco Dynasty 43 that is significantly heavier than my old Contessa. Its tires were marked 5005 to 1006, so too old to have on a new-to-me coach, so I asked for Michelins. I was told it would be 4 to 6 weeks to get Michs, so what other brand would I take. 3 others were on offer. I took Toyos, which, at 4500 including mounting and taxes, beat the FMCA or Monaco Michelin price by over $1500 (8 tires). Once the coach arrived, the universal opinion gathered from all my ORI neighbours who came around was that Toyos are just as good as Michs, so save your money. Those prices were arranged by the dealer, so YMMV.
