The distance from khi to quetta via rcd highway is 750km approx. While if u go via jacobabad i.e. Khi-jamshoro-sehwan-dadu-larkana-ratodero-shikarpur-jacobabad-dera murad jamali-sibbi-mach-quetta is 850kms. I prefer the latter route. Its safe in my opinion and u get to see many cities in ur journey in case of some unexpected emergencies/problems.
If ur going via khuzdar you can have a stopover at khuzdar only if u can speak sindhi or you have family with you. Avoid socializing with anyone on route. If FC tries to stop you than REMEMBER to stop else thay have orders to shoot the vehicle. Levies police wont be stopping you if u have family and hopefully FC wont as well.
Take ample water supply with u because til quetta you wont find any shop selling nestle bottled water. And snacks as already suggested.
In my case i stopover at larkana for night and leave larkana by 8am and by 2pm i can reach quetta. If u want to go this weekend through MY prefered route than we can go along as well.
