Finally got around to figuring out how to get the drawer off it's tract so I could take a photo for you.
The cabinet measures 45 3/4"x 27 7/8", the butcher block top 47 11/16" x 30 1/4.
One picture is of the interior of the left side of the cabinet, there is a partition between the left and right side of the cabinet. If you look to the back of the interior the little black objects are the closure locks, you can see there are two for each drawer except the middle one there are three for the weight of the pots and pans in that drawer.
The convection/microwave oven is the standard Cuisinart for 2016 that Airstream is using and the bezel dimensions are 17" x 24". The dimensions for the drawers are the face dimensions, the interior door dimensions are a little smaller. The bottom openings are flip downs, they are shallow due to the wheel well behind them.
I did a little sketch with some dimensions, if there is a measurement you need, let me know.
We have spent ten days camping in our trailer since we got it, we love the dinette set up, we seated six for dinner in the dinette, to give everybody more room, we set up a ZIPDee lawn chair. We could squeeze seven at the table, with the lawn chair if necessary.
One item we would like is lighting over the butcher block work top. I am currently looking for a light for that area. I think we will use LED track lighting and plug it into the inverter circuit when we dry camp (about 90% of the time.)
