i was looking at this tent myself only last week and i was told by the salesman at our local winfields store that they can take the kids room, in the end i opted for a gelert beyond corvus 6+2 as its that bit bigger, however i do believe the monty is the better tent
Yep it fits, we had a 2010 Montana, the kids room fit 90% just need to swap the clips from the old bedroom straps to the kids room. Otherwise toggles etc all fit. 5/10 minute job and it's in
