My take is this, unless you have a good need, your better off saving the money and getting a F350/3500 gasser for occasional heavy tow. I would even say that if your in an area where the break point of paying a LOT or not so much for truck registration/annal taxes, you may be better with a F250/2500. I ahve my diesel because the price was right, and pulling a 14k 5th wheel, I do not think the gasser would give me the 10-11mpg I get with this setup.

If your going to see significant towing in the mountains I'd go with a Diesel. You could also upgrade your trailer weight without concern later.

My experience is exactly the same, although I had a 5.7 hemi and now have a 6.7 cummins and the years were 2011 and now 2014.

For me it was worth it, overtime the fuel saving and the additional value of the truck when 5 to 6 years old I will more then have my money back.

@ 4 mpg increase and $0.50-$0.60 per gal more cost for diesel, it will take many, many years, if ever to justify the cost while towing only.

I have the old 2001 F350 Lariat 7.3L 4X4 pulling a 16K loaded 5er toy hauler and it gets 9 to 10 mpg depending on the hills. She only has 133K miles on her but I'd like the newer 6.7L Ford diesel because of the power increase they have, but think I'll keep drivin what I have because the price of a newer ones has gone up so much.

Just have to include my two cents:

I was a stubborn gas guy...then along came this 2011 F350 Lariat (new!) for a great price and today I would not go back. I pull a Cedar Creek 36CKTS and get 10-11 MPG with it loaded. I used to pull 25' TT with a 150 and only got about 7-8 MPG. BTW, the 350 "doesn't even know" there's a fifth wheel behind it! I'm sooo glad I came into the light! Beautiful TV! (and sounds cool too...gotta's just purring "what we gonna pull today?")
