To be very honest, 4x4 keeping is easy if you get it revamped and like this you would know what jobs you've done, and how's the quality of the vehicle. If everything is maintained you will enjoy your trip alot.
Like going from Islamabad to skardu via babusar in only 45k diesel. And visiting khaplu, shigar, Kachura lake. And Then climbing deosai, and most importantly choosing a hill of your liking and take your jeep there enjoy with your family and friend, no pressure of jeep waiting time where jeep driver continuously says sir andheray hojaega jaldi karen.
So completely soothing experience, it is to have your 4x4 and enjoy. Like if I had visited on my car so I would have spent around 40-50k fuel, and then I would have taken a jeep for deosai, for about 25-30k plus another hassle my car would have been parked in skardu so not going towards other side ie astore valley. However on my jeep I crossed deosai and visited astore and stayed there and next day came back to babusar. So it's a great feeling.
And it is definitely worth the cost.
Now I've got another one, a three door LJ71 aka prado 1990, it has some maintenance works to be done, then I've plans to explore its drive in north.
