What is the longest sewer hose you can get? It seems like in most RV parks we've been to lately, it's a long way from the outlet on the Rv to where it goes into the ground. What size do most of you ha...
Use hoses that have molded in connectors and join them together as needed. There are a few poorly designed RV parks we've been to where the connections were to the far rear of the site and 20' wasn't enough. My 5'er has its connections on the side just in front of the tires. This location seems fairly common. I have 2 10' hoses that have worked at the majority of parks.
