Great post, Hanif bhai.
Your ride problems are going to give me nightmares as I do road trips with my family too and I am afraid of all these problems that I wouldn't be able to diagnose if my car breaks down.
Last year my EE80 shut off at a village somewhere near Multan (I headed multan through Head Punjnad bridge route to avoid smog in November). It was a fuse that was connected to cng converter switch that broke down. Fortunately, there was a tractor mechanic that helped me fix it.
I have a question about Ishkomen, how is the road condition? Can we take a car there or 4x4 is recessary?
