I don't know a good article, but for some reason I was curious at one point and discovered the marketing pages for various big rigs. Marketing materials presumably showcase more flashy features and higher trim levels.

Also the /r/Truckers/ subreddit has users post their setup sometimes. But usually those are either "look what I was able to cook" or "check out my gaming setup".
