Every 50 miles I'm stopping to let the diffs cool. It's been a long 300 miles back home. Worth it through. That's numbers I haven't seen in a while. The best average after all the additional farkles was around 15.6. The engine and transmission behavior is also better. Staying in the lower RPMs without the occasional shift into 3500 - 4500 RPM range.
Set up complete cooking system that keeps the bed clear and is part of the Tacoma's EDC. It includes a MSR Whisperlite Stove and fuel, Snow Peak Personal Cooker cookset, Tembo Tusk Adventure Skottle, and Mountain Hatch tailgate insert. All of it hung on Grayman Tactical Molle panels.
As a bonus. Since the speedometer gear housing is on the transfer case changing the gear ratio has restored it to be about 2 mph lower than what the GPS was reading. I don't have to do the 8% adjustment in my head anymore.
