Those coffee van set ups are pretty legit and a lot of work goes into them. It's Basically a mobile deep cycle battery with a massive inverter and the coffee machine and stainless steel cabinetry, benches and the coffee machine sit on top. I've seen some with a solar array on the roof to charge when stationary but most operate off the battery system that charges as they move.
I'm glad someone caught my coffee-girl nectar comment. Lol.
Yeah that sounds like a pretty impressive set up. The solar panel idea is cool. I wouldn't be surprised if that becomes more common in the future.
I think so... A little set up and running cost but no expensive leasing of premises to worry about.
