Greetings & Welcome!
I’m a huge fan of the no build builds. Just move your furniture in and secure it.
It can time & experience to decide what we really want and/or need, and this can vary for each person. While I’m never a big fan of built ins, I really wouldn’t suggest it for newbies. We see people all the time with multiple costly time consuming builds as they gain experience.
In the end they’re ditching solar, lifepo4 batteries, 12v compressor fridges, and basically ALL of the expensive stuff in favor of old school & reliable.
