You actually touched upon a small annoyance with Host campers in regards to hose storage. The black tank is in the driver's slide and eye level (nerves like Hurt Locker) and the grey tank valve just below. It's a stretch for the typical hose to reach and if there are fittings of size on either end, forget about the using the factory tube.
I have a container with lid that has fittings, gloves, clamps, and a back-wash valve that's usually stored in the basement. Not anymore. There is also a narrow storage slot option for the tailgate located in front of the camper jacks that will fit our small fold-up table.
I don't even have it mounted and already I have it half loaded. Douglass builds a nice truck body with lots of options including custom.
