I agree with you about water but someone just went to Gwadar in March 2018 and he told me that Pakistani petrol is available in Gwadar. see the last reply in this thread: https://www.pakwheels.com/forums/t/gwadar-ke-sayr-march-23-2018/782735/316
About Gwadar: well Dubai wasn't built even 20 years and Dubai had many other factors for its development. And i m not interested in any kind of investment there but thanks for alerting me.
Yes its is little rushed, hopefully i will stretch this plan to 10-12 days and u know most of the things are decided at run time by looking at the ground situation at that time.
Thanks again for your comments, its really gave me confidence that my plan is doable.
