Settle an argument for me, please!
My buddy and I have been arguing over this for a few weeks and I keep telling him that he is wrong about this. He says that I should not drive with the tow-haul on all the time because it hurts my MPG...

Are you sure your buddy is not confusing tow/haul mode with the OD switch. The OD switch pretty much just prevented your tranny from going into OD, creating higher RPM's and bad fuel economy yet needed when pulling heavy loads. This was all back when trannys did not have all the electronic stuff that they have in them today. If he is thinking about the OD feature then he would be correct.
Now with the electronically controlled tranny's the tow/haul mode switch came out and operates completely different than the OD switch ever did. Others here have posted how this works and I don't think the switch affects mpg that much. Just use it when needed to get the best life and fuel economy for your RV.
As far as the post above with the Ford and the OD being disabled when in tow mode, not sure about that. I have a 2011 Jeep GC, 2010 Dodge Ram Cummins and my 2011 Ford Class A. None of these vehicles disable OD with the Tow/Haul mode switch on.
