This RV should be removed from any future rentals until the electric wiring harness is replaced. It is not safe to drive in mountainous/hilly terrain. For the vast majority of the rental, the check engine light was on even though the engine ran fine. The worse problem is that the ABS light keeps clicking on at the most inopportune time. See attached photo. When this happens, the transmission goes haywire - downshifting and upshifting sporadically - and impacting the ability to brake properly. This is a safety hazard. The cruise control will not work when the ABS light is on either. In addition, there was one time when the ABS light came on and the transmission would not shift out of low gear. At this time, the check engine, ABS, and emergency brake lights were all on and the speedometer registered zero even though we were moving at 25 - 30 mph. It was questionable if we could get back home. The worst part is that the owner is aware of this problem and did not bother to inform us prior to the rental. I paid for a working and reliable RV and did not get it. Good Sam needs to investigate this and make this right.
