I believe that when a manufacturer recommends changing oil every X thousands miles or every Y months, whichever comes first; they are assuming that the time interval catches the person that puts on very few miles a run cycle. When Ford built the engine and wrote the manual, they did not know that the engine was going into a MH that would be driven for 300 miles and then parked for a month.

Just curious if your DD takes the 42-47 quarts of oil as described by DD. I would suppose that with that amount of oil in the engine, 25k to 50k would be be plausible. That makes sense.
I know of no oil that can go 35k ( with no more the 10 quarts utilized in an engine) unless the oil is recycled through an external filter and detergents reintroduced and the filter is specially designed for long term mileage.
The oil sump is 50 plus, takes 41/42 at change.
