We owned a Rayzr FK a couple years ago. Just be aware that Travel Lite is prone to be a bit misleading in their advertised dry weights. The Rayzr was advertised as 920 lbs but actual weight was about 1,320 lbs. This was determined on a Cat scale coming home from the dealership before any additions or modifications (actual dry weight). We actually sold the unit before camping in it mostly due to design factors I wasn't comfortable with and the huge amount of drag produced by the large frontal area.
