I couldn't agree with you more. In fact, the only reason I went with a 8ft bed was to get the bigger tank and to be able to put a transfer tank in the bed and have room to store s

I am in the process of moving and instead of paying $8000 for some retard to break my stuff I decided to do it myself, since I can break it as easy as they can

I have to make about 6 trips at 550 miles one way pulling a small trailer over about three months to do the deed. I just couldn't justify having to stop every 300 miles for fuel. The other thing is that diesel down in the south is much less expensive than it is in the midwest because of the state taxes. I can fill up my OEM tank and my 50 gallon tank down here and take a load and return (1100 miles) on one fill up. That is about $316 at today's prices. That way I can stop when I want to stop not when my truck tells me to stop.
Another irrelevant factoid is that the new F150 Ecoboost that came out in 2011 had a short tank in it too, for only ONE YEAR (in the short bed model), then they started to put the 37 gallon tank in it in 2012. The tanks are not interchangeable, how dumb was that. That was the main reason why I went to a SD plus I was not getting the super-duper-supercalifragilisticexpialidosius milage that they were advertising. I got 14.1 and they were advertising 17 in town and 21 on the road. If you read on the F150 forums, about half are getting fantastic milage, some as high as 22 on the road and 18 around town, then there were trucks like mine that were getting 14, 13 and even 11. So the Ecoboost engine, while being a good overall design, is not operating like Ford had planned. Even the 4 cylinder Ecoboost is not getting OMG milage like some of the small V6's of other brands are getting. Ford has always had problems with fuel economy compared to the other makers, for some unknown reason.
