The tubes being broken off would worry me. That doesn't sound normal. Valves are usually located right near the end of the low point drains.
Take a look under that rig and see if you can see a red and blue tubes that are the low point drains.
It could be some type of bypass system or overflow, but it's only a guess since I don't have your rig.
Try contacting Forest River and see if they'll authorize a mobile mechanic to come take a look.
