I have a 190V '95 Dodge. there is a very active RT group on Facebook. I have 107K on mine and the garage put 5W30 Mobil 1 in by mistake 3 years ago. They offered to change it and I said I would try it to see if it ran through oil. It does not require any oil in 5000 miles and my mileage jumped to 16-17 with a 318 and driving 60-65. It is a lot smaller than my Mountain Aire was. My wife always said when I would die she would get a Roadtrek. She died 5 1/2 years ago and I got the Roadtrek. At 81 I am happy with it but still miss a large MH.
