On my 2012 Crusader I see that the slide outs already have the rail for a cover attached to the trailer above each slide. Are these ready to use for a new slide out cover? Will either the Dometic or Carefree of Colorado fit the rails?
My 2014 Crusader has the mentioned rails which were factory installed . They were indeed used to install the Dometic slide toppers. They were installed at the dealer.
