Couple looking for advice/info

Hi there! My boyfriend and I are thinking about RVing as an alternative to the outrageous rent prices and terrible roommates of San Francisco Bay area. My only experience with rv's is camping in my grandparents small one over 20 years ago.
We are looking for advice/tips/recommendations/tutorials from you all.
What kind of rig to look for, buying a used rig, life at rv parks, urban rv parks (we still want to work) etc.
Tell us your stories!
Thanks in advance!
Sarah & Felipe
