Thor 29M 2019
We had our kitchen drain shear off at the gray water tank on our 2019 29M. I took the advice from another forum to use a 1 1/2 inch swivel. It worked great for four times retracking and extending the slide. On the fifth time out the pipe sheared again. The cause is that big bundle of wires and hoses. It dropped down behind the pipe causing it to shear. I then took a large tie wrap around the bundle and drain hose. It keeps it off the pipe but still loose enough to flex. Hopefully this will fix the problem. I will say the open compartment is way too tight.
