This appears to be one of the small negatives about the design of the "recreational utility vehicle", i.e., Axis/Vegas. Those F53 based rigs sit up much higher and also have the more intricate sewer dump systems with the hose wash out option, etc. The E450 chassis sits lower, therefore probably drives better but then causes the sewer to be closer to the ground. This makes the process a bit of a pain on the knees. I'm learning to take some of the minor negatives in stride.
