Had a few issues with new unit. Only 2 gave us fits. The batteries stopped taking a charge from the converter and when hooked up to the truck the aux. fuse in the truck would blow when we tried to use the hydraulic pump to bring in the rooms or level the camper. Had to buy battery charger to keep batteries up. Turns out there is 6 rubber covered fuse type connections above the battery and the one that feeds voltage back to the battery was tripped. You had to remove rubber cover to find small reset button. Took dealer 2 hours to figure it out. Worst problem was hydraulic lines to jacks. One completely blew off the fitting and 2 others developed bubbles and they blew. Camper could not move till mobile hydraulic guy put 3 new fittings on. He showed me where two other hoses were soft. Seems the crimped on ends were allowing fluid to back up between the outer and inner hoses. I want the dealer to replace all 12 lines to the jacks and the lines to the motors that power the rooms. I will wait to see what the do.
