Tuareg for 2up

Hello guys. I'm looking to buy my first adv bike, I come from Enduro but I fell in love with the old Tuareg when I was young, now im looking for a bike to commute and eventually travel a bit with my girlfriend, does anyone has experience with 2 up in highway? Is it decently comfortable? I don't plan on doing more than 300km in a day but possibly steep mountain roads
