RhinoFLEX kit seems very durable. Only had it for 2 months and I’m a full-timer. Usually, end up repairing a hose about once a year, but for a couple of bucks more I can buy a kit like this one. Only time will tell how long it will last. The clear elbow is always a plus nothing like watching your crap go down the drain, but seriously you know when your tank is somewhat clean. The only thing I don’t like about the kit or in this case the fittings is they’re about a 1/4” too big to fit in my bumper storage. Can’t believe they couldn’t have made the fittings just a little small in diameter. Thank goodness I have a dedicated tote for carrying such items, otherwise, I’d be quite pissed off when I got ready to pack up and found the damn thing would have to ride in the back of the pickup bed. Then again they do come with end caps which is a good idea and something I’ve never seen before.
