Hello Everyone, my wife and I have owned our 2008 Supernova 6400 since late 2017. We are trying to get involved with other Supernova owners especially the 6400 series to see what they have done to their rigs and maybe find out some things to watch out for and get ahead of. We love the tank capacity and sleeping capacity of the rig but would love to get more power, better weatherization, and smoother ride if possible. Looking forward to hearing what everyone has to provide.
