I purchased a 2014 rushmore lincoln on July 6 of this year. I can only speak to my experience with this unit. I have used my unit 3 times already. I have spent one week at myrtle beach and 2 different visits to pigeon forge. When I got home with my unit I found that a technician had hooked up the battery backwards, this ruined my external radio but was replaced by me dealer. I also had a few led lights out in my awning, a small crack in the bathroom door and a broken outside storage door holder. Everything has been fixed by my dealership prior to my 2 trips to pigeon forge. I have used my air conditioners (both of them) on all 3 trips with no issues. They kept the unit very cool at myrtle beach when the temp was above 90 everyday. This past weekend we used the furnace 2 different mornings in pigeon forge with no issues. My wife stated that she liked this furnace better than the one in our cedar creek because it was quieter and heated the whole unit evenly. All 5 slide outs work perfectly so far. I know that there could be more issues in the near future but right now i am very happy with the unit. I did purchase a 5 year extended warranty. I figured with 5 slides, 2 inside frigs, 1 outside frig, 3 tv.s and all other appliances I may get my money out of this warranty. I just hope my dealership continues to take care of me.
