I fall into the camp that stretches the interval between longer when I don't put many miles on. Over the years we have averaged 10k per year and changed at least annually. Now we sit more than we travel, by choice, but travel longer distances per day yet so I will go out to two years between, but not longer. I've supported my thinking with oil analysis and am comfortable doing this.
I'm currently at 99k on this coach and have never had an engine issue related to oil on any of the three we have owned.
As to what the OP should do, I would simply say weigh all the advice with your own logic and decide what you are comfortable with.
