Through the years, I've read many posts slamming Lippert, especially for their frames. So with the experience with Lippert support that we just had with my son's hydraulic Ground Control leveling system, I had to write. First, the system is out of warranty. Second, the fault eventually was discovered to be not even caused by a Lippert component. Now with this understanding, Melvin with the support team at Lippert took multiple phone calls from us, walked us through multiple troubleshooting scenarios and finally led us to the problem: improper wiring from the factory on a four year old Sierra fifth wheel! I know y'all are amazed to think the factory may have put out a less than perfect unit (smiley face). The hydraulic system has never really worked correctly, but we just thought it was the limits of the system--slide outs timing out before fully extended, the jacks sometimes doing the same. But then, worst of all, it blew out the control module. Then we started calling. After we replaced and corrected all the wiring and replaced the module (which Lippert gave us!!) everything is literally better than new. I really am amazed at the extra miles Melvin took to solve our problem. So kudos to Lippert Support!
