This is extremely disappointing news. I'll share an email I got after asking Rad Power about Legacy Caboose availability:
Hello Jason,
Thank you for reaching out to us. I am happy to answer your questions.
Based on the information I was able to find, we will no longer be stocking the Legacy Caboose anymore. This is due to the global supply chain issues occurring. As well as a higher than normal demand for materials that is making it harder for us to source enough materials to continue providing this item at the current time.
I am going to close this ticket for now. This isn't to say the issue is resolved. This is just to avoid you getting emails from us. If you have any questions or concerns please reply back to this email and it will reopen this ticket for us.
Regards,
Robert

Yeah, I agree this is disappointing. I'm in a similar situation with the legacy Deckhand. I have a Caboose, but my kids have outgrown it and I need two legacy Deckhands and can't get them :/
Anyone want to trade? 2 legacy Deckhands for a legacy Caboose?
I'd be interested in buying your 2018 caboose
