I like what Rory Irish (#TrailMater) said about Toyota 4x4s.
"Oh yeah, they're great off road trucks. After you replace all the running gear with Chevy."

Duramax diesel in my TB. 2022 refresh. With 1400 miles just did trip of 300 miles and got 29 mpg! Mostly highway cruising at 72. Impressive!

VSE Recently released some tuning for the non-refreshed truck/interior LM2's, as well as transmission tuning. up to +50 hp +80hp. LZO and Refreshed LM2 tuning, and turbos are in the works. IMO as long as its in warranty, Its staying stock. As far as MPGs go I have been averaging 20-22 in town stop and go, and 30-35 on the highway is achievable depending on wind and such.

I wonder what MPG the 3.0 could achieve in something a lot more aerodynamic than a truck with big tires? Is 45-50mpg realistic?
