Confirmed, 18.0 mpg...
In another trip from KY to NC. Route 460, pulling an utility trailer with a clotheswasher, a portable generator, a mower and many tools, hilly terrain, mostly at 55mph, airconditioner on.
I have no front wheel driveshaft nor wheelshafts , and all brakes are confirmed not dragging, 82C / 180F inline thermostat, running steady at that temperature.
Lowest octane fuel price in KY: $4. Fuel price in NC: $3.50 /gal
Without pulling a trailer and on flat freeway terrain, am confident will hit over 20mpg. Will tell whenever have real numbers.

On a related note, I ran a tank with no front shaft, and my mileage went up 0.5 mpg in mixed highway/local driving.
It's hard to imagine pulling the front shafts would have such a profound effect.

It'll be fine, I drove 15 hours in RWD at 70-85mph
My suggestion is to get front axle shafts in, the hub bearings could possibly separate without the CVs and nuts holding them

having done both. front wheel drive and rear wheel drive only, at times. front wheel only= I could notice I got much worse mpg. rear= same maybe better.
a lot of burning off in front wheel drive.
you do know that you can buy an adapter for the lt230? makes it full time 2wd to 4wd

There is no way you can get 18 MPG.
I got 16 MPG tops towing NOTHING and going 55MPH and no faster.
And I was pizzing off everyone going 55MPH.
I did this with 3 tanks of gas and could never top 16 MPG.
Towing - there would be no way to even get 14 MPG.

If he's removed all of the rotating mass between the front wheels and the transfer case, and the CDL is locked during, then yes, a substantial gain is possible.
That said...
Without the front axles in, or at least the axle end past the CV joint installed and the nut torqued to the required 360ft.lb., your front wheel bearings will separate at some point, and you will have a bad time as a result.
