Yes, I agree, but with the delay in sale, I'm also enjoying the drive pleasure & economy.
I'm not in a hurry, I have already planned a visit to Islamabad at start of 2016. But if I prepared it for long route, it will increase demanding price.
Just completed a trip of 160km (approx) without A/C in full cylinder (8kg / 8.5kg) = 19km (approx) and still it might cover 4 to 5km more.
