We looked long and hard at the Navion 24G and just wanted a Ford or Chevy chassis, not MB, for a lot of reasons that have been discussed ad infinitum on these forums. We have had three Bs and three Cs over a thirty year period and the fit and finish on the RT 210 was the best we owned. That being said, with the changes in ownership of the company I hope the quality stays OK. For years, the family that started and owned RT just kept the same basic models and improved them a little every year. Now, there are a lot of different models both on Sprinter and Chevy chassis.
I will add that the Chevy 6L has pulled us over most of the really tough and high passes in the Rockies with that 210P fully loaded with all our gear and it performed well for us. If we didn't love our new Phoenix Cruiser 2350 so much, we would buy another 210P in a heartbeat.
