Mine has the cover, which is easy to remove, but even then it's in a tight spot between the tank and sidewall. The tubing 90's straight up from the fitting and under the bathroom sink. I believe you're the one who originally helped me dissect the plumbing on this thing. Hoping to disconnect it from the antisyphon valve, remove the flush nozzle and take the whole assembly out, tubing and nozzle. Can't do it now cause we're camping and I can make due without. The gray tank is easy to get to, the black tank nozzle is forward of that hatch opening, back right wheel as yours probably is. Been a while since I had the cover off, I just remember it being a little cramped and thinking if I had to remove it, it wouldn't be just terrible. We'll see soon enough.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
