Good opportunity- need suggestions

I have a 2016 TRD OR that has a timing cover leak and I’m at 55,000 mi so getting it done under warranty.
Have a friend that’s a senior tech at a large so cal Toyota dealer That’s going to do the work that I have total confidence in but while it’s there I’m going to have him do several other things.
Front brakes, full tune up including plugs, belts and hoses, tranny flush, radiator flush, change out the oil in the diffs and Transfer case, lube the driveline, install ECGS bushing for upcoming lift install at Accutune,
Brake fluid flush, have the cab mounts and radiator mounts checked.
Any other things I should consider
As I’m keeping this truck and want everything possible looked at and serviced while I have this excellent opportunity to have my truck gone through.
Any other things I should be looking at..??
All suggestions welcome
TIA.

 

Since you're changing your fluids, don't forget about the power steering fluid.
