Most Endurances have a microwave above the cooktop. Those micro units have tiny vents and fans, and Hampton does a good job venting this air outside the boat.
However, those small vents don't really do the job when one uses the cooktop. So I wanted a real vent/fan setup, called a "power pack" in the home building industry. It's a nice Broan unit with an infinitely variable fan control as well as dimmable lights.
The factory did a nice job finishing out this space around the fan, and we selected plastic bins to keep everything in place. I have my cooking oils, vinegars and other non-refrig condiments. In the beginning I had these spice bottles in a bin, but that meant to get at any of them I had to bring down the entire bin.
At some point I realized the bottles could sit on this "shelf" area, I just needed a way to contain them. I first looked into a plastic rod, but it got kind of complicated and was going to cost several times to ship what the plastic cost.
My good friend Don had been doing some projects and had some extra metal rod. He cut it to length for me, and I painted the rod. It sits right on the hinge, I just used a dab of silicone seal to secure it. Now I can easily access any of them.
Did a lot of cooking on the trip, of course, and this area makes everything so handy. Only problem was that when I got home I had to relearn where everything is in the home kitchen!
