This is the 24 ft. Slate Edition special model. I bought it in early 2022. It was owned by an engineer who had installed a $20k solar panel add-on. I have put about 14K miles on it and it runs great. 3L 6 cyl Mercedes diesel engine. Close to 20 mpg. Drives like a large SUV or pick-up. Everything works. Priced to sell: $129,000 OBO
