If the size of a bed is important to you, measure the beds.
Queens are sometimes not really queens and I don't just mean the length as in 'short queen', measure the width.
Regarding corner QB floorplans in the Winnies , we found some of the Winnie queen beds that were really doubles. It appeared that it was done to offer a little wider shower in corner baths.
Being that we spend 8 hrs in a bed and 5 mns in a shower, we opted for the full size QB. That's one of the reasons we went with a Forest River full size corner QB.
