A few questions
Now it seems you have a little time off from the driving, perhaps the team could share some thoughts on the vehicles?
You are in the fortunate situation to be driving a modern truck with quite a lot of engine power. Obviously this makes more relaxed driving, knowing that there is no challenge in high headwinds, long uphills and other situations that require power. But what is your actual driving speed, are you going faster than other (older) overlanders you have met on the trip so far?
What is the mpg you are getting with these trucks?
If given the chance, would you attempt the same trip with less engine power - more in line with most 4x4 had 15-20 years ago?
Have you fitted larger wheels or are you using stock size?
So far the trip has taken you thru the civilized part of the world, with a gaspump available in every town. But when you hit the more remote part of the world, what is your range between required refueling?
