Newbie: it appears tank hoses don't come with new trailer

Thanks. Do you recommend getting the hose supports or is waste of space?

I recommend getting one. Unless you think you will enjoy "walking" down the hose lifting it as you advance towards the drain pipe. Many sewer hook-ups sit 4-6 inches above the ground which is code in many places.
The accordion style of hose supports are light and don't take up a whole lot of space.
