https://www.rvingplanet.com/compare-rvshttps://gorving.ca/compare-rvs/https://www.gorving.com/explore-rvs/compare-rvsI have a 2018 Navion 24V on a 2017 MB Sprinter cab chassis and it's been fine. Maintenance intervals for oil changes and stuff are longer than gassers, so that keeps them closer in costs, and I'm in Canada and diesel is cheaper here than gasoline, another perk, and my fuel mileage is almost double most gassers, again a perk. I tow a Wrangler 4 door with it.
If you're familiar with diesels, and don't fear them, I've had both and love the Sprinter over the other gas options. Twin beds, separate lav and sleeping area, galley and living room.
Price on used might be your only problem. I see them holding their value on the RV sales sites.
Mike. Comments are anecdotal or personal opinions, and worth what you paid for them.
