2009 Holiday Rambler Navigator Bismark IV powered by a 650hp Cummins ISX diesel and an Allison transmission on a Roadmaster chassis. The standard generator for this unit is an Onan QD 10KW on a power slideout tray. See below for more information and the unit is located in Valdosta, GA. Batteries will need replacement. Interior and exterior cosmetic condition look pretty decent (typical wear). Unknown electrical issue. There is a power draw on the batteries (even with cut-off switches turned off). With good batteries the unit does start and run but there is a drivability issue due to the electrical issues. We could not get any power to the slide outs and generator and couldn't get the generator to slide out for inspection. Miles unknown and actual generator size is unknown.
