Hello, I just brought this unit home, wow its a dream to pull and my 02 2500 Dodge Ram Cummins TD done a great job! It is a beautiful Unit both inside and out! I will be on the phone Monday though.... When the brakes release it sound like a lot of metal clanking around in the drums and the generator is showing 27 fault code.."controller unable to sense output voltage". It did this yesterday at the walk around but the guys said they corrected it. Today it will not stay running..same as yesterday and shows code. Is there a quick fix as manual says contact Onan? I also wonder why the lock ring on the very expensive 50 amp shore cable has been either removed or broken off? Plus being as I am older..lol...I've forgotten what some of the control switches do already and some are not detailed in the Owners Manual !! All in all I am very impressed with the unit as are those who have seen it, very good craftsmanship and materials used are top notch. TomL
