Okay I now got it down to very minimal creaks, there is still some but only if I really listen for it. A big improvement from my initial experience.
Thanks to gtalum for pointing out the overhead sunglass holder and ravnlunatic for the rubbing on the center glove box. I totally forgot the I had my sunglass in the overhead holder. I have not been wearing them lately due to cloudy days and I was too busy listening to the creaks and other noise in the cabin... oops.. :lol:
I've fixed the center glove box noise with some chair foot pads placed in the right locations. I got some extra since I dont have that much furniture.

I spent everything on the RAV4, paid cash. My second home is my RAV4. :lol:
Anyway, now my newly redesigned, newly bought RAV4 feels much more solid. Another advice to others is to put a hand towel in the center glove box, it deadens the noise a bit more and it prevents the contents from moving around (an making noise), plus you'll have a towel when you need it!
Thanks again, sometimes you just need some other person's perspective.
