I would say look at Newmar, Winnebago, Tiffen, Fleetwood Bounder. They all come in gas and diesel. Do not buy the Tiffen FRED( front engine diesel) they are so loud you cannot hear yourself talk.Country Coach are great but extremely expensive. I buy used but check for maintenence records and how it was maintained, have a RV tech check it out and a motor mechanic, test all electricals and appliances and water. Check for water leaks with staining on ceiling, check walls on outside for warping. Get up on roof and check the caulking, and tears etc. There are check lists on the net for Pre Delivery Inspection (PDI) they help!
