My wife and I own a Fleetwood Bounder (gas) and are looking at full timing in the not so distance future. I'm doing research on the pros and cons of each and thinking that diesel is the best way to go. I would like some thoughts from experienced RV'ers as to costs associated, i.e. maintenance and fuel milage, with diesels and any comparisons between the two, gas and diesel. Also, if anyone has suggestions as to manufacturers of diesel and what to look for if looking at a used diesel. Thanks.
