Yes that recent video is the one I posted. Where both Ford says and TFL admits they were over spec due to not RTFM. They were quite a bit overweight and over SAE speed and grade.
Great video, but a bit mistitled imo. If you truly want to build it (rather than fitting a very nice fully pre-fabricated wedge tent to a Jeep), and can afford to invest substantially more time to realize substantial money savings...
