We considered these for a brief time when looking to upgrade from our old Aussie Jay's soft floor (bearing in mind this is our home as we live on the road). Things we noticed in our research watching others and looking at them in showrooms:
not enough storage for everything....nowhere near
setup time similar to ours
inside kitchen
annexe area too small...we live outside and only use the inside of our tent for sleeping
wasn't impressed with quality of cabinetry and fittings
not (in our opinion) up to the rough roads we regularly travel for the next xxx years.
The only real pro for us was that they're off the ground.
We've paid the deposit on and looking forward to December delivery of a Cub Spacevan hardfloor with bunks as an option. We seriously considered a Drifta DOT (not enough undercover area) and the Ecomate forward fold (heavy, not enough storage, liked the two awning idea but not enough space with the main one on).
