Our Honda's have an onboard computer that tells us when to change the oil, usually it's around 7,500 miles but it can be less or more depending on how the car is driven.
Our MH has a Cummins engine, Cummins says every 15,000 miles or yearly for oil and filter. Last year I did and oil analysis, if came back "run the oil another 5,000 miles and recheck" and that everything looked normal.
Maybe those of us that go longer on the oil changes do it because that's what the engine manufacturer says to do.
