We have as 4 yr. old Holiday Rambler, Endeavor.. and the same thing happened to our slide out covers... only on all four of them. They started to tear at the edges...the one on the drivers side has completely torn from the casing..... we called our extended warranty and it is not covered... "CareFree" points the fingure to the manufacturer, stating that they just supplied the material... to get this replaced on all four is going to be around $3000.....! Any suggestions on how to do it ourselves or contract out at a cheaper rate would be appreciated.
