Best dump hose length

I was at a park recently that had the water sewer and electricity in totally random places. I just couldn't figure it out but the camp host cleared it up when I was chatting with him. It was an old manufactured home park. The homes were hauled off and it had been re-purposed as an RV campground. Not surprisingly, they didn't want to spend the money to move everything to the traditional locations. So, yes, extra hoses of all kinds can come in handy.
