I had the same issue that you describe in the center console. I found some silicone spray 'safe for plastic use', and sprayed it under the trim area that the noise seemed to originate from. That totally cured it - been a year and still no squeaks or creaks from the console. If you try it, make sure you use a silicone spray that is safe for plastics.
That's very good to know if I don't get rid of the truck. I think having all this plastic on plastic is just a bad idea.
Thanks a lot!
