Hi,
I carry 1 10 foot, and 3 25 foot. I also have a 50 foot "wind up" fabric hose. Ideally I would go to 1 10 foot, 1 25 foot, one 50 foot and one 75 foot.
I carry a 25 foot black hose for flushing the waste tanks.
I changed the sink in the commode to a garden hose thread, and when there is no flush water I'll use my on board hot water to flush the waste tanks.
It's a good way to find out how much "time" you have for water use. My pump operates for nearly 30 minutes on a full tank of fresh water.
Regards, Don
