Our 2008 3000RK had a hydraulic leak from day one. Took it back to the dealer under warranty, they finally agreed to replace the line from the selector valve to the main slide. Got the 5th wheel back home and backed it into my shop, checked and still had the leak. Called the dealer, they sent their service manager to my home to inspect the unit, he agreed it was leaking. I returned the RV to the dealer, everything was replaced except the selector valve, new hoses, new pump, new rese
voir, so far seems to be cured.
