Is the microwave strictly a microwave or is it a combination convection oven/microwave? We have the combo and I must admit for our first two years we never used the convection feature and only used to microwave to heat water or a hot dog and re-heat coffee. We finally got out the manual and learned how to use the convection portion and now use that feature more than microwaving. At first I thought it was overkill for a B but now have changed my mind. In reality 99% of the time it is our bread cabinet.
There is a certain elegance to the curvature of the upper cabinets. Our GWVan transitions a bit more clunkily but I have come to dislike a shelf with a variable depth dimension such as we have. You cannot plan and store modularly very easily. Do your upper cabinets have a variable depth?
If we buy another B, after 8 years of always having electric sofas converting to queen beds we are thinking of a twin bed design. The tri-sofa is nice and makes for a nice, more open living space in the back, but we end up one person in the back and one person in the turned around seat in the front if doing things like reading books. The sofas have never been that comfortable for watching TV so we ultimately turn the bed down to watch. I don't think we would ever sit sideways on the seats or entertain back there as the back bolsters imply. I think I would want something more along the line the Winnebago ERA 70A plan offers for twin beds, higher with more storage underneath with more upper body shoulder and arm room. One thing for sure, having a fixed queen bed or the sofa converted bed that you have to crawl in and out of is starting to get old with us. One trip I over extended my shoulders scooting out of bed and they hurt the whole trip. Most every ERA couple I've met never fill in the notch to make a full bed.
