Street Side Top Down
Driver Side Top Down
Front to Back View. I think the couch/sofa is mis-sized, but it works.

Back to Front. That's the entire galley. I'm wanting a simple setup. Most eating/cooking/stuff will be done outside the camper.
And the Pop Top raised. Overall it's 18". Only about a foot will show.
Comments and suggestions are welcome.
