I have wasted so much money trying to get good mpg out of big trucks - mainly after believing peoples fairy tale internet mpg claims. Once it gets to real world driving, there just isn't a lot that we can do (that makes sense money wise) to get ahead.
Now... If you want to mod it to make it drive or pull better, and can get a bit better mpg out of it, that is a different ball game, and is fun.
