Adrian,

You don't have to change hubs, but what about the stud diameter. I could be dead wrong, but I think you have 1 1/8 studs. The new 10.5 wheel will have 7/8 studs. requiring you to  replace the studs in the hub. Then the old wheel won't bolt up.

But if the coach already has 7/8 studs then I am wrong.

My 99 has 1 1/8 inch studs.
