Sorry for the late reply ... been out of touch ..
Anyways i would recommend that you should take you own Prado, the roads would be fine in one months time as told by the local people ... what I understood over there was that the local people create a environment that its very hard to take visitors own jeeps cuz they want to rent out there own jeeps at HIGH rates .. what i believe is that if you have good head on your shoulders you can certainly drive your own 4x4 to these places ... until and unless you do some thing exciting
Well as I said earlier .. take your Own jeep ... If 30-40 years old jeeps can drive there then certainly your prado can ... when i was entering Naran there is a Large glacier and when we approached it there was a long line of cars on one side and on the other side there were 5-6 local jeeps parked and they were telling the vistors that its impossible to cross the glacier in ones own ride even if its a 4x4 ... and even stopped me that you cant cross and its better to park the LC here ( parking available instantly for 500 night) and then jeep would charge 150 per pessenger to take u across
... so u can get the idea why it was being done ....
What i did was simply put it in low gear and crossed the glacier with Ease
and the looking at me the rest followed ....
So my Dear Friend .. take ur own ride 
Hmmm .. well as i was there the roads were being worked on and very soon they would be ready to be used ... so i would differ and recommend to take his own prado ... Prado are meant for these roads and trust me nothing happens to it ..
Thanks Sir jee ... Well we found the tasty trout at he stop over in between naran and kahghan ... he had both local and farm ones ... local Rs 1600/kg and farm one Rs 1100/kg ... and you can easily see the difference
.. tastes Amazing ...
Thanks Bud ... i was soo excited to drive on it that did not take pics 
Well we took a route form Manshera And hasanabdal while going and on return we took -Garhi Habibullah - Muzzafarabad - Muree - Isd - Pesh ...
If you want to avoid traffic while taking the Hasanabdal route .. the trick leave early and cross mansehra till 11-12 ... then u are just Fine
I AGreee !!!
