I don't have anyplace to set things(bottle, shot glass) when sitting at the front gaucho, so I'm thinking of adding those cabinets to use for that purpose. It would require notching the ends of the rail on the front of the seat to allow the bed to pull out over the top of them, and they can only be about 12" tall and 5-1/2" deep, but I think they would be very useful. If I build them right up against the front of the gaucho they will look original and I will still be able to open the storage compartments and pullout the bins. with the bed open they will be covered up and provide support for the ends of the bed platform.
I haven't thought much about the countertops yet. The original countertops are light brown formica with a "T" molding edge, 1" thick in a matching brown color. I could do the same thing again, and I probably will on the kitchen counter, but I'm partial to wood so I may do the other counters in the same wood as the cabinets but with a more durable finish.
I'm amazed at how light the cabinet construction is in airstreams. I will be setting up a construction template in my layout program so it will accurately show the construction and give me a cutlist for parts. I would guess that the cabinets in my trailer weigh maybe 150 to 200 pounds. the same cabinets with my standard cabinet construction would be 450 to 500 pounds!
