I've been looking at the Montana and I really, really like it, BUT it worried me a bit that there was no 'porch' bit to leave all the wet wellies, coats, etc. I've only just noticed the Sun Valley 6 which seems to solve that problem - it looks like a Montana but a smaller living area (which is probably fine) and the added porch bit. Does anyone have one and would you recommend it? Does anyone know if the bedrooms are as big and high as the ones in the Montana? And would it be too fiddly to put up?
