Welcome welcome!! Thanks for choosing to be a CrossRoads owner!
The Rushmore line was actually renamed and consolidated in to the CrossRoads Cameo line. So, going forward, many of the floorplans and features that were favorites in the Rushmore line can be found in 2016-2017 Cameo 5th wheels.
Not sure what the exact reason for the consolidation was, but we have gotten some good feedback thus far!
Should you ever need any warranty help with your Rushmore, feel free to shoot me a message. I'm here to help in any way I can!
