@Ehalin, corolla will not touch the road. Just be careful after Jaglot there are under construction culverts and you have to cross these by undulating the car like a fish...it will not touch then.
The trip is doable in 4 days and to do it in this time span is a personal choice. I will not prefer...when I am out, my prime purpose is to unwind, change my routine...do not drive the way I drive to my office...prefer dinner at a spot on a deserted highway...mm alam road is not my choice then.
