I love mine. I removed the shorter tube and installed a longer piece that I got from Camping World. I cut it just long enough to fit my Rhino hose. The newer Rhino hoses have a translucent elbow that works OK.
Several parks I have been to all I have had to do is swing the arm and connect to the sewer with very little hose to pull out. Most of the time I don't have to use any extra hose support. What I like is that the hose is attached and stored in the same tube. The only thing I have to do is attach the elbow. I find it very convenient.
KTManiac did the same mod I did, however he used the whole tube and supported it at the end. By cutting mine, I didn't have to support the extra legnth. Here is a link to his photos
