We had to replace the square sewer tube caps on our 2010 EggCamper. The plastic lost it's plasticity and wouldn't grip the inside of the tubing any more. Replaced them before we lost the sewer line. Relatively inexpensive:actually, those rubber caps hold quite securely when they are popped in ad the rubber is still fairly fresh. sure, in 10 years, they get old and hard, then they fall out too easily.

On our Escape, we secure an inconspicuous little wire spring clip through the lock hole just in case the plastic latch works lose while we're on the road.
