DFWTerry-
First off, welcome to iRV2!
Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are

Re: HR info.
1)
Here is a link to the contact page for HR Parts.
2) The HR owner's manual Web page (link
here) only lists manuals for 2021 models. It used to allow access to manuals from 2000 model year onwards. Something is "broken" on that page. That said, a 2021 Vacationer manual is available for download (link
here), and may have information useful for your 2015.
3) I suggest you call HR Customer Support (877-466-6226) and ask them to fix 2), above, and if they can send you the owner's manual, build sheet and window sticker in electronic form. The build sheet should list the awning make and model. This assumes HR still issues build sheets and window stickers.
4) Although not related to the awning ID issue, the HR Technical Support folks may be able to send you wiring diagrams for your coach. Ask the Customer Support person for their telephone number.
5) You may find a label on one end of the awning roller [I realize this might be a problem for you, as you can't open the awning to find the label.]. If there is one, it may list the manufacturer, model and serial number. Carefree of Colorado made the awning on our 2008, but that may not be the same for your coach. If it is a Carefree of Colorado product, plug that serial number into Carefree's tool (
Here's the link). This will tell you the model for the awning. From there you can download the manuals, part lists, and the like. I have called Carefree a couple times, and received helpful answers.
Note: The 2021 owner's manual implies that model year uses a Carefree of Colorado Travel'r awning. The link to that awning's product page is
here. Does it look like yours? There's a link on that page to replacement parts.
