"Reducing the height and width of the car can reduce the frontal area, but there is a limit to how small this area can be since people must be able to sit comfortably inside the vehicle. Therefore, the easiest method of decreasing drag is to lower the coefficient of drag of the car [3]. The coefficient of drag of a vehicle depends predominantly on the shape (Fig. 2). Therefore, vehicle designers change specific aspects of the shape of the body of the vehicle in order to reduce the total aerodynamic drag and thus increase fuel economy."

For the ultimate mileage, remove the windshield wiper arms and fold the side mirrors in
I am sure there is some give & take in Vehicle design between what is visually appealing, is quiet, roomy and etc and also economical and able to be mass produced at a profit.
a lowered vehicle may scrape on the ground, be more prone to collecting mud & dirt and water exposure, etc...

Exactly what I wanted to ask @Rocket Man about.
I was mentioning that because those would be reasons why oem would not produce them like that if they can help it, the T2's do now have automatic lowering, not to the ground lowering but they have came around to the benefit.

Just buy a mini van

Um, no thanks?
Last time I hit a small pothole with a minivan, the minivan was all,
'Wanh. I need a new tire and strut.'
The Z71 thinks it's just a bump.
Again, wonder how @Rocket Man 's feels about it.

I was referring to lowered SUVs. They look like mini vans and have about the same people/cargo space.

Ah.
In that case, yes, minivans become much more competitive with LOWERED bubbas / XLs.

Wha? Why would you ring me about ANYTHING related to MPG? I’m running a cam, blower, headers, etc and lowering was done to improve looks and handling. I get about 8 mpg depending on how I drive, I can get a 10mpg average if I stay off the pedal long enough but I don’t and I don’t care.

Guess you lowered 'em AFTER pumping up the top end? OK. Figured I'd ask.

I gained 2 MPG when I lowered mine and removed the roof rack. I also reduced the rake, but kept a noticeable amount. The rake angle is a factor in their aerodynamic design. Level or worse, squatted, would increase drag. They have a little more rake than necessary to have more rear travel when loaded or towing, sacrificing a tiny amount of optimum aerodynamics. I rarely tow or haul and have air bags so I opted for maximum slipperiness. The 22s cost me a solid 1 MPG.

[Not really an] Update:
Yukon is in the collision repair shop (thank you, ma'am, for not knowing how to leave a parking space without scraping my bumper) for 2 weeks. Will have to wait to install CAI.

The Yukon is back from repairs and paint, ready to install CAI. Except I need to get myself psyched a bit more first. I have no garage, nor even a carport, nor even a tent (I had a superb and affordable tent not long ago).
When I don't mind the weather quite so much, I'll swap to the [dry---no washing and oiling required] K&N CAI and let you have a listen/look at the results. TTYS!
