I guess by then on my ‘06 the engineers allowed that the dolly system was ill-conceived, as I don’t have that contraption... or it wasn’t needed on our particular model configuration. The water hoses were never an issue but the drain was. I replaced it in 2012 while on a trip. It was a learning experience.
Suffice it to say the longer the drain hose the better, so it has a large loop to spread flex forces along. The factory hose was several inches shorter than it could’ve maxed out at, and maxing out is necessary to keep it from crimping over and eventually splitting. Some here have converted to a different type of hose, but “tacky” rubber risks retaining debris inside over time, whereas slick-lined flexhose drains clean.
If you still want a photo I can probably try to supply one, but as noted it’s likely not exactly the same setup. It may provide insight or ideas. But getting a good angled photo shot with useful lighting I’m not sure about.
