Where the hose comes out of the tank, it sticks straight up, making it hard to coil around. I cut it, inserted a plastic 90 degree elbow, and solved that problem. They have those showers custom made for Duckworks, so he may have them make that mod on new ones.
The yellow you can see is new- that's a pressure release they have on the newer tanks
They have also introduced a "quick connect" fitting as an option so the hose can easily be removed for storage.
