I was wondering if there are any alternatives to the regular coiled sewer hose commonly sold in RV stores. My mom has settled in to live year round in an RV resort and has been lucky to get 9 months out of a regular sewer hose (supported by one of those sidewinding plastic supports). Is there any type of hose that is more durable and weather resistant (Florida heat and sun) than the usual stuff? Any advice from some of you long time-RV'ers would be much appreciated. Thanks!
