Thanks for your nice words,
Yes it was not easy ride for the wife but since she share the hobby of travelling, she manages happily. "Shoq da koi mull nai."
Just once I engaged 4x4 on a steep wet slope full of mud while going to Bamburet Kalash. After engaging 4x4, vehicle climbs it like a charm. I was willing to descend back and climb again to take maza of 4x4 but evening was approaching so let the idea go 
So happy with the fuel average, for example I got the tank filled in Chitral, then go to Bamburet (rough track, 1st, 2nd gear), Back from Bamburet -> Drosh, Lowari Top (whole rough track, 1st, 2nd gear) -> Timergara -> Mardan Rashkai Interchange and then got fuel tank full again on Motorway and it was 29 liters from Chitral to M1 including Kalash.
Total distance covered during whole trip was 2179 km, fuel average I got is 10.3 km/liter and please keep in mind it include several long rough tracks where you are limited to travel in just 1st or 2nd gear like upper Yasin Valley, whole day route of Phander to Booni, track to Kalash, and also Lowari Top.
