Hi there, We tried to put up our bag awning (manual put up) on the 2015 Rockwood Freedom 1640LTD this past weekend. We are missing one of the vertical poles that provides support from the front of the awning to the ground. We have three for one side and two for the other. Where can I find these replacement parts, and what are the actually called. I thought it was vertical support poles, but that is not bringing anything back that looks like what I have.
