Slide out awning

My living room slide has developed a leak. When it rains water pools on the front 24in or so of the awning, then leaks onto the slide and eventually into the living area. I took it to a local RV dealer (not Camping World) to see if the topper could be tightened or adjusted to prevent this. They contacted Dometic (the slide topper manufacturer). Dometic said that because the topper was over 190in long it should have had a cradle installed. The awning tube was bent because no cradle had been installed from the factory, and my extended warranty would not cover the cradle because it was a modification according to them. And (according to the woman at the dealer)they would not cover replacing the tube because it would just bend again(?) I am willing to cover the cost of the cradle if my warranty would cover the bent tube.
