So, what is your advice on rv’s and what to get?

so i recently was scrolling on some rv selling websites, and i noticed many different models, etc. etc. but what is the best rv that is good fro just… living? what should i get for something that acts as a permanent home, AND something i can move? i know it sounds dumb, THAT’S WHAT RV’s ARE FOR but… which one is the most livable?
