Miles Per Gallon - Your Results

While staring at the road while on a long trip towing my 5er, I got to thinking about whether I get good miles per gallon on my truck. So, I thought this thread would be a good place to ask the question "What is considered "good" mileage?"
To do that, I created this little form (see below). Would some of you please fill it out for the benefit of all of us? That way we can compare how we are doing in our towing efficiencies. Best way to do that would be to copy the block below in your reply and insert your own relevant information. I will insert my own information after this blank template. Please give as much info as you know.
Thanks in advance!

Year, make, and capacity of tow vehicle:
Weight of tow vehicle:
Engine and fuel type:
Weight of loaded trailer or fifth wheel:
Average speed while towing:
Average terrain (level, hilly, or mountainous 'L,H,M'):
Average Miles Per Gallon:

Average speed while towing: 65
Average terrain (level, hilly, or mountainous 'L,H,M'): L

I have found that slower = better fuel mileage. Wind drag has a HUGH effect for me.

Interesting that you have a Smarty installed. I forgot to mention that I also have one on my truck, and mine is also set at level 3. That extra 100 HP is noticeable.
