Hi There, We've owned Vanguard and Okanagans, both quality Canadian built 5th wheels. We now own a Carriage Compass, a quality built USA 5th wheel. Many of the high end manufacturers went under around 2009 - 2011, so if you are in Canada you could look for a used Citation Supreme, Corsair Excella, Triple E Topaz. All rated for 4 season living, when you skirt them in and wrap hoses etc. Even on Vancouver Island they had a lot of snow last winter and freezing temps that froze water lines in rigs that were not prepared for winter. All the best in your decision. This is just our opinion.
