Hi everyone, great website. Have just purchased our first motorhome, its a 3 year old Roadstar 786 and love it. The only trouble is there was no info left so we don't know how to operate anything! In particular twice now we have woken up to a flat car battery. I'm pretty sure it's user error but any suggestions would be most helpful, thanks in advance. Also help regarding the 4 digit yale alarm and the computerized thing above the door would be most appreciated! Very Newbie...
