Exterior Sink Drainage Coachmen Leprechaun 319mb

Any recommendations for automatic tire inflation adapters for dualie tires?

Thank you for your replies. I’m taking it in for service under warranty. But I’ll remember the light snake idea for future.

area below slide out tray is open so get under there and remove/disconnect sink drain line and check for obstruction/blockage

Could be drain line is 'pinched'

Warranty service. Easy to determine if they fixed it. Runnng a very light duty snake down the drain as a last resort.
