Welcome Amber and family
You're in the right place. Have you got a particular bus model in mind? You'll get lots of opinions on what might work best for you. We like to ask if you've got a safe parking spot for your bus? What are you mechanical and build skills? Stuff like that. It doesn't really matter what your skill levels are because anybody can learn to build a bus.
Are you guys planning on using it like a weekend camper or are you thinking of a little home on wheels?
