Jayco Greyhawk black water tank

[Larkspur]

I recently backed up my 31fs. Unfortunately I backed into something that pulled my back water tank drain from the shutoff valve. The tank is now at an angle, and I cannot get the tubing to hook onto the main drain. When I go to push the tank back up into position, it's hitting something. Is it possible that the vent tubing is hanging up somewhere?

You might want to post some pictures. Kind of hard to guess.

Enjoy the journey
