Rewalsar to Dharamsala distance is 154 km approx.

I started solo from Rewalsar by Royal Enfield Thunderbird Twinspark motorbike via National Highway 20 and reached Dharamsala in 5 hours 30 minutes.

It was the rainy season and few places there were landslides.

Maybe if no rain then from Rewalsar to Dharamshala 5 hours will be the total journey hours.

Rewalsar to Manali distance is 135 km approx.
