I looked at those a while ago. I like that large vestibule space - but there's no way I'd be parking my bike in there. There's a reason I park my bike 6ft or more from my tent... if it topples during the night it's not going to land on top of me.
Still, the vestibule is good... but... the tent is heavy, more than twice the weight of my current tent, which has more sleeping space... and it's only single layer (no fly) so I don't know how well it works for condensation and water resistance.
I like the name though!
