(The tonneau cover cost me ~$80 for all materials at home depot.
If you're interested, I'll take some pics of it. It's a very simple design,
no drilling in truck, very light, etc., but still pretty user friendly)
One thing you should know is that I'm at high altitude (~7000 ft average).
That definitely plays a role as it effectively turns my 3.5L engine into a
2.8L (there's about 21% less air up here...less air means less fuel) and it means less wind resistance. I also have a pretty favorable commute as it's all rural highway (50-55 mph) with some good hills. The hills enable me to use DFCO and EOC at strategic spots. It is, however, only about 9 miles if I take the long way, so I don't get the long commute advantage and my winter mpgs will go way down as the engine will take the first 5 miles just to warm up.

How confident are you on that altitude figure?
I'm trying to figure out how my 2.3L Ford Ranger is getting 60 mpg hwy in Jackson, WY (besides all the aeromods). So my engine is really like a 1.85L here at 6,500 ft?
