20/23 there is soo much untapped potential .. 39.9 City(Actual at the pump) and 27.8MPG Highway 59MPH with CC is my best Almost 40MPG out of it in the city (at 41MPH with cruse control 0% grade) 0MPH wind...

You do not have fuel logs, in fact, we do not have any reported Tahoe hybrid fuel logs, the average reported fuel economy on EPA.gov is 23 MPG, and the average reported fuel economy on fuelly.com is:
18.1 MPG for 2008
18.57 for 2009
None for 2010
15.32 for 2011
None for 2012 and
18.35 for 2013

65MPG  @ 70-75mph(v4 Mode Cruse control OFF) tailgating a 18wheeler with a trailer-tail.. the ones with out the trailer tail offer zero benefit. even a loss of mpg slightly about 1-2mpg (at 25-26mpg)....

In what world is drafting a more aerodynamic vehicle infinitely better than driving behind one that leaves a bigger wake?
Zero benefit. People with poor decision-making abilities have been doing this for decades.

* In scaled wind-tunnel tests, driving 100 feet behind a semi at 55 mph will reduce drag on your car by 40%. The drag reduction increases as you approach the bumper of the truck until you get a 93% drag reduction at a distance of 2 feet.
* In road tests, the testers achieved an almost 20% improvement in gas mileage at a distance of 100 feet (at 55 mph) and a 45% improvement at 10 feet.
Tim also calculates that at 100 feet you have 1.25 seconds to respond if the truck slams on the brakes, (keep off that cell phone) and at ten feet you have .124 seconds. The recommended distance at 55 miles per hour is 150 feet.

so 40MPG/27.8MPG is possible under "hypermiling"..
40MPG MY City/65MPG HYW under SUPER hypermiling drafting

Get out of here with your drafting MPG. I am sure that a hummer would see "decent" fuel economy drafting a semi. Do it long enough and either you have a friendly chat with the back of a trailer or a highway patrolman.
AutoTrader said that there were honest gas savings with the hybrid Tahoe (over the gas-only one), but I am not sure that it would have paid off. The LS started at $36,500, but the hybrid started at $50,500, and gas dropped below $1.60 a gallon.
They said the hybrid increased fuel economy from 16 MPG to 21. Sixteen MPG at $1.60 a gallon (I miss those days!) is 10¢ per gallon. Twenty-one MPG at that same price was 7.6¢.
You would need to drive forty-two miles to recover $1 of the $14,000 surcharge. You would have needed to drive 588,000 miles to break even.

Yes, well, new SUV buyer's thoughts are not my thoughts.
Used, though, it sounds much more reasonable. I got a KBB price for one Tahoe, but just errors when I tried to get the other. Nada Guides says a 2013 LS is worth $15,500 and a hybrid is valued at $18,650.
The average gas price in the U.S. today is $2.838. The gasser would cost 17.7¢ per gallon and the hybrid would run you 13.5¢. Saving 4.2¢ per gallon, you would need to drive 75,000 miles.

By the way, you an hypermile a gas-only Tahoe, too.
