Hello. I am new to this board. My wife and I have RVd for many years. Tents, Travel Trailers, Gas Motor Home and presently a 33' fifth wheel that we pull with a F350 Ford Diesel. We can get anywhere from 9.5 to 11+ mpg. We REALLY want to purchase a used diesel pusher motorhome. BUT...with fuel prices as they are...it kind of gives me the jitters. What type of mileage might I expect on say a 40' Beaver or similiar Motorhome? Some honest opinions would be appreciated! Is this a great time to buy or should we wait and see where in the world fuel prices are going. I don't want to have to spend $1,000.00 or so to have to "fill r up" if you know what I mean. Also the value of the motorhome concerns me if prices do go on through the roof. I know that no one really knows, but I would appreciate some feedback. Thanks!
