Im conflicted on this point. I find convincing arguments and anecdotes for doing it according to the book or the old fashioned 5,000 miles (or whatever it is). We used to have a 90s caravan that made it to 300k on original trans and engine. The last 100k had 3 or so oil changes. Got rid of it cause there was a brake leak hidden somewhere. Still drove strong.
In the end, it is a call you are going to have to make.
On the 2011, I follow the max mileage allowed or 6 months, whichever come sooner for oil changes, doing brake inspections and other preventative maintenance along the way. Transmission and transfer case fluid is is every 30,000 miles. Rear axle and front axle is based on when the maintenance charts list them but they have been changed well before the recommended mileage. On the 2019, I've had to modify the maintenance schedule a bit since very little mentions anything about time change intervals. Just mileage.
An honest transmission shop will tell you that they would be out of business if people changed their transmission fluid every 30,000 miles. Most axle problems, especially those with limited slip differentials, are due to people never changing their axle fluids.
Vehicle manufacturer's want people to buy their product, so in order to make them seem more convenient, they have stretched out the fluid change intervals more and more as time has gone on. Sure, oil has gotten better since the 1950s and 1960s but it still wears out and gets contaminated from combustion byproducts. Never the less, change recommendations like 10,000 miles or once a year for oil is just insane. The mileage recommendations for transmissions and axles are the same. Some recommendations, like the rear axles being "the life of the vehicle" are purely meant to cause the vehicle to wear out and break so you will want to buy another one.
Plus, they don't say what "life of the vehicle" is. Just after you paid it off? 10 years? I'm sure they don't mean 20 - 30 years like the typical owner on here has in vehicle age.
