6 month (10,000 mile) warranty service recommendations?

Bringing my DCSB OR in tomorrow (at 8400 miles) for its 6-month warranty service. Besides the typical fluid and filter changes, and the all important free driver’s side floor mat inspection , what other non-typical possibly free items do you suggest asking the dealer to check or do on it?

I tow and go off-road with it, and have had no problems with it so far, but it will be interesting to see what they say about the new KO2’s (free rotations gone?) and the 5100’s/Dakar AAL’s (suspension warranty gone?).

Edit: just saw this post too, https://www.tacomaworld.com/threads/what-maintenance-have-you-done-so-far.529586/ where bshammer0 recommends:

Tighten U-bolts
Grease U-joints if you have zerks-(I don’t)
Rotate tires every 5k
Replaced my failed CKP sensor (mines good)
Replaced my failing battery (ok)
Cleaned by oily MAF that came from the factory with residue on it... (not sure- is this a common issue???)
Change my engine air filter (ok)

any other suggestions appreciated.
