My RV uses a spring cylinder on the interior cabinet doors to hold them up. This device has a standard coil spring inside of a tube. These springs look and work very much like the gas spring cylinders. I like the real springs because the gas/oil will never leak out and cause them to fail. The gas cylinders seem to fail at the worst times. They also don't hold the load as well in cold weather. I wonder if they are made on the larger sizes needed for you bay doors? It looks like the door on your generator compartment will be under a slide out. You might want to consider converting it to cafe' doors so that it will still open with the slide out extended.
Maybe this link will work to show what I talking about.
