It depends on what people are online. The diesel people will say to get a diesel and the gas engine people will say go with the gasser.
Why not tell us how you plan to use the coach. How many miles a year? Long trips or short trips? Full time or part time? Children? Can you do your own maintenance on the coach or do you have to pay others to service it? Does new furniture and appliances matter to you? Some people refuse to use an old mattress. Where will you store the coach when not in use?
Answer these questions and you have a better chance of getting a better reply.
