Art, on mine just the pump motor failed (pump worked fine using my Dewalt driver and manual operations). Happy to be picking up the trailer this morning from the service center. On my trailer there is only one system (larger tank, but just one motor and one pump) for slides, landing gear and Level-Up. I guess all I can do is hope that the pump I had was the one made on Friday afternoon
. The manual operation works fine but takes a while and not something I want to have to do too often. -Glenn
