Well, I FINALLY caught up to y'all on your trip and great adventure over the last year and a half by reading here and there every night for almost 3 weeks. Feel like I've been on an intercontinental trip myself!
I've also spent a night "sleeping" in my car, although this was in the mountains of Shenandoah, Virginia after a large black bear knocked down our tent with myself and my girlfriend in it. That was nerve-wracking enough, I can't imagine if it had been a pack of lions we were looking to keep out. That begs a question though; what, if anything, have you had for protection from animals of the predatory nature this whole time? Spray, sirens, blunt objects, bare fists? I figure you've now gone through some of the most diverse fauna in the world and I'm surprised your run ins with mother nature have been so tame!
I was also sure you'd have to break out your winch when the 4WD went, but alas you bested the terrain! And, on that note, best of luck to both of you and please continue the excellent collection of photos!
