@ shanii123
thanx for appreciation bhai 
you travelled 10k kms wheras in 1 strike the distance is aproxx 2600 km frm khi to khunjrab pass
bhaiyya main Khi say nikla to naak ki seedh main to khunjerab pass gaya nahi
it was a pak tour 71 days long
in which i went to many places not only the khunjerab :d
now please apprise that at how many places else stright journey
bhai continuous dirving ki jitni himmat ho 
what was the situation of fuel (petrol+disel) and cost of it
petrol diesel is easily available in Abbottabad, Mansehra, Besham, Dasu, Chilas, Gilgit.
after crossing Gilgit u'll find pump only at Aliabad ( hunza) n then Sost 
while driving in hilly n landslide areas always try to drive between full n half tank 
also intimate the availablity of motels and their fairs
regardin accomodation
PTDC motels r available there at Besham, Aliabad (Hunza), Sost. i personally don't like PTDC as they have no quality:(
Serena Hotel Gilgit, Hunza Rupal Inn Gilgit (better than serena gilgit), Hunza Baltit Inn ( Serena Hunza), Hunza Darbar Inn ( better than Serena) at Karimabad Hunza. 
many more hotels ( 4 star to no star) r available there according to someones budget 
what about the food all within the drive
food is available at road side hotels within the drive :d n its normal
safar main nakhra kesa 
are the people hospitable..
kisi kurri ko na chairo
then they r more than hospitable
