Good one! I am getting roughly 15mpg right now after adding a Dobinson suspension lift with 285/75/17 KO2s. I’ll update after a proper check.

what would be helpful is if everyone popped down to their local scales and weighed their rigs. While gear ratio and tire size and speed are big factors- weight should be factored in for anyone driving anything other than dead flat zero elevation highway,
The weight info per axle is also incredibly helpful when selecting suspension/springs and shock valving.
Seems like it would be helpful to track the weights of aftermarket equipment in the new thread so we can calculate/approximate our adjusted rolling weights. Particularly the aftermarket equipment that is >50 lbs.
I am curious what the weight difference is when changing from air suspension to coil suspension.

Just did a small 400 mile road trip over Christmas and averaged 22.3 mpg on the expressway doing 70 mph. Everything in stock until next week when I get the KO2’s on.
2019, 255/70/18's (32's), no lift, roof rack or bumpers. We see 16 in town and 17-17.5 on the highway. Worst I have seen was 15 on a trip south into some very strong head winds. I can live with those numbers, but sadly I bet it drops a few MPG's with the addition of a rack and lift and should we bump to 285's in the future I bet we'd be looking at 12-13 at best.

I got 19.5 mpg on 265 70 17 BFG KO2’s running 70-75 mph on the expressway on a road trip.
When I divided the gallons used vs actual miles I got 19.9. How accurate is everyone’s display screens?
*update
We've had the 285/70/17's and 2.5" lift on for a month now and I am consistently seeing 14.8-15.2 mpg in town and 15.2-16.2 mpg on the highway. I'll admit that is better than I expected and more than acceptable by my standards lol.
This is about what I'm getting roughly. Similar set up.
13.5 ish mostly city / 14.9 ish highway

Adaptive cruise set to 70, but in SoCal, so there is always slowing traffic.

I have been tracking all my fill ups on my 2013 GX460 for the time I've owned it.
100% stock, no plans to do any other mods for now just because I don't want to nuke my fuel mileage and the DD comfort.
So 20-21 mpg fairly easy to achieve as long as you stay at or under 75 mph.
