- 0:35Mac and TJ introduce the unlimited-budget season and the Cummins Patrol's low-range upgrade plan.
- 1:43Mac attempts a steep rock crawl in low range without touching the throttle.
- 9:04Clearance problems force a switch from twin transfer cases to rebuilding the existing single case.
- 14:10The supplied reduction gears turn out to be the wrong ratio for the revised plan.
- 15:18Work shifts to fitting an electronic locking differential in the rear housing.
- 16:33Max delivers custom exhaust parts for Mac's planned twin stacks.
The Patrol crawls up the rocks without Mac Preston touching the throttle. TJ Jack's verdict is simple: "It just walked it." That is the starting point for TJ AND MAC's only upload this week, before the truck goes into the shed for considerably more work.
"Unlimited Budget Cummins Patrol (BUILDWARS 3)" opens the new season with ambitions for two transfer cases, lower gearing and more control. Unlimited money, though, doesn't create unlimited room underneath a Nissan. Clearance and a tight deadline send Mac back to a single transfer case, then the gear kit turns out to contain a different reduction ratio from the one that plan needs.
Josh from Geared Up Drivelines helps strip the hardware and set up a rear electronic locking differential. Meanwhile, Max from Hyfab delivers parts for twin exhaust stacks. Those stacks have given viewers a very specific finishing request: several want flapping covers on top to complete the truck-like look.
The episode has reached about 156,000 views and is comfortably the channel's most active video right now. Behind it, "Striving for 1000hp! (6.7 Cummins Chevy)" keeps the diesel projects moving, while "Dream Backyard Shed Setup!" offers a tour of the space where this sort of ambition lives.
The channel added roughly 1,000 subscribers over the week, half its gain across the past month. Its weekly views also sit towards the stronger end of the nearby travel channels, with Riri Travels having a larger viewing week and Lvfree Adventures seeing little change in its usual daily pace. For TJ AND MAC, this week's trip was mostly from the rocks to the hoist, with plenty to sort out in between.
