Tire rotation with duals

I only rotate tires on anything as needed. Usually less frequently than recommended by mfg. Yes to even out tread wear if tread wear is a limiting factor. Also in some cases to prevent tire noise. The motorhome will probably get the fewest rotations of my vehicles. I fully expect to condemn the tires due to age prior to the worst one wearing out. My only expectation to rotate them would be if the front tires unexpectedly develop heavy cupping, feathering, or some other issue which leads to noise or poor ride/handling. In that case I'd probably rotate them front to back. I've seen no signs of these issues so far.
