You will go comfortably in 2007 city.
Road is in good condition except khi-hyd and lodhran to multan is very bad. Multan to lodhran is newly built.
multan- khi is more better than khi to multan. Specially entering sindh and then till hyd was a shock for us. It was too good.
khi-multan is 14 hours of net driving. Multan to khi is 13 hrs.
if you hit the road around 7am you will easily make it will little driving in night time
I observed that night time driving is more difficult due to HTVs. They'll frequently disrupt your momentum
Sukkur will be the approx mid point. You can easily find a guest room on the main military road. We stayed at the decent lounge (main city branch) @ 2000rs ... but the the military road decent lounge has a very easy approach. Book in advance to avoid any exploitation (just in case)
Avoid eating on road side dhabbas although we did
keep dry fruits, fruits, dates, biscuits ..... stop for tea only.
anyways if you still want a proper dinner then sajjad restaurant in thehri just before sukkur will be a good option (have not tried myself ). its the same like the highway restaurant here in khi
NOTE: STICK TO N5
GOOGLE map is a very helpful
make sure you have car cellphone chargers
