Sounds like an epic ride, I'm feeling adventurous when I do a 2-3 day ride.
I've got a sudden urge to get hard panniers to go with the top box.
I nearly went down a few times on a few clay patches on a dirt road about 3-4 weeks ago, I had to use dirty puddle water to clean the chunks that fell on the chain and I only got about 1/3 of the amount of clay on my bike as compared to what you got there in that picture. I'm not sure how I didn't drop it, I had the bike at a 45 degree angle at one point, but somehow it popped back up at the last millisec, I suspect the tyre hit a rock right when I was working the bars and putting my foot down to put me upright again.
Like the website says "Enjoy life, ride a motorbike".
