Maintenance on 2006 Tundra

I've decided to keep my 2006 Tundra instead of buying a newer truck. It only has 53000 miles and had the frame replaced for the recall a few years ago. I'm willing to put some $$ into it to keep it reliable. Can someone suggest a list of inspection/replcement/repair items that I should consider that would minimize the chance of an unexpected failure?
Thanks for any advice.

 

Change all fluids- diffs, xfer case, trans- all drain and fill, no flush. Lube any suspension and driveline zerk fittings. Change spark plugs, air filter and cabin filter. If you have the v8, change the timing belt, due to age not the miles. Look over suspension, change out any worn bushings. Check drive belt and tensioners, replace as needed.
