Mystery Drain Hoses: Starcraft AR-ONE 14RB

Depending on where they're located they are either low point drains or fresh tank overflow hoses.
If they are low point drains there will be some valves above them in the trailer. If they are overflows they will be near the gravity fill for the fresh tank.

If you think they are overflows just overfill the tank and see if water starts pouring out.

You are correct. That valve is labeled "low point drain."

Which is why I am curious about the other two drain hoses . . . they are not mentioned in the manual under "winterizing" "plumbing" or any other heading.

Does anyone actually have model specific knowledge of these hoses and can say with all certainty what purpose they serve?

(If not, I'll just call the manufacturer on Monday AM and report back for the good of the order. Happy weekend, everyone!)

Cheers!

They appear to be low-point drains used when winterizing your trailer, or for any other reason you might find to drain the water lines as completely as possible. There should be valves above them inside the trailer.

They kind of look like the hot and cold low point drains, but I would go topside and see where they originate from that will tell you for sure. JMO

Those are cold and hot water drain lines. They are similar on my 14RB of another maker.
