What are the arguments pro/con between owning a Ford 250 with a 6.8L V10 Gas vs. a 7.3/6.0L Diesel. I plan to pull a fifth wheel in mountains as well as flat lands. From the forum I read that the Ford 6.0L Diesel may still be in potty training with problems. When I buy, I'm looking to be pulling 12000 to 14500 in 5ver trailer weight. Since I'm also looking at a short bed Ford 250 with extended cab, I like the idea of the Pull Rite SuperGlide (16k). Is there a forum consensus yet on hitch types, or manufactures. The hitches are pricy, but sounds like an addition worth the money. What's the forum's thoughts? Can anyone suggest a list of 5ver makes for fulltimers? I'm a newbie and I hear that you better look for fulltiming certification when buying.
