I myself due more frequent fluid changes whenever I can. Changed the oil, diffs, and transfer case fluids before first 2000 miles just to make sure factory crap was out, proper level was in, and to get rid of any initial factory sediment/break in shavings. The rear diff is easier to change fluids than a regular oil change IMO, so I have changed it about every 10-15k miles. Figured it's a traditional rear wheel drive, and most of the wear will be in the rear. I do the front diff and transfer case fluid every other 10-15k miles when I do the rear diff. Again, for me, it's easy to do, easy to get the fluids, and gives me peace of mind. Is it overkill? For some maybe. For others it's a no brainer. They don't build them like they used to, so I figure fluids is the easiest thing to change and invest in the vehicle.
Now, the transmission service is a little bit more involved, and the fluids are not 'as' cheap, so this gets done less often. YMMV.

Some owners don't plan to drive their vehicles more than X number of miles before selling/trading it in. What is the value of X?
IFF X = 60-80K miles, here are your folks who might do nothing...while also installing a K&N, cuz, well who cares. It won't be their problem.

I agree with this ^^

I used to and still have this attitude I didn't buy my vehicles, only to take care of them for the "next" guy But I have noticed that 'they don't build them like they used to' seems more prevalent now, and I find myself doing more of the simple PM things for "my" benefit and hopefully get a better vehicle ownership experience when I still own the vehicle. I still couldn't give two what the next dealer or owner wind up with, as long as I benefit from it in the long run.
