I made another similiar post on this site, then I noticed this subject. My wife and I are considering buying a large 36-40' diesel pusher. A used Beaver is top on my list. Are we crazy to be considering this with fuel prices as they are?!!! We presently own a nice 33' fifth wheel and tow it with a F350 Ford diesel. We average between 9-11+ mpg. What type of mileage might I get with a diesel pusher? I realize that it depends on driving speed, towing or not towing and what type of terrain. I am of course concerned about what the value of the motorhome would do IF prices for fuel keep going up and up. Your thoughts and advice would be greatly appreciated! Thanks!
