So I talked to nuCamp about my concerns with the Air8. They cancelled my 2020 order and placed me on an order for a 2021 that should be commencing in the next few weeks. He still wouldn't tell me what changes are being made or what a/c they will use, just that prototypes are in production. I told him my final decision would hinge on whether they are still using the Air8. He wouldn't/couldn't say so directly, but I got the impression it would be something else.
