Advice Itinerary Ideas for a Bergen Campervan Trip

We're renting a campervan in Bergen at the end of April and are super excited! We have about a week to explore, and I’d love some recommendations for a route that includes stunning fjords, picturesque villages, and maybe some hiking spots. What are the must-see places we shouldn't miss? Are there any hidden gems or scenic campsites along the way? Any tips for traveling in a campervan in Norway would also be great. Thanks in advance!
