Dometic's A&E brand window awnings can be purchased and installed at Camping World. I have seen Heartland coaches with a single manual pull-out window awning that shades both windows and I have seen Heartland coaches with individual manual pull-out awnings the shade each window individually.
Both seem to work well. I like the looks of the separate window awnings but my sense is that it is easier to roll out one than two awnings and cost-wise, one may be a little bit less money.
Carefree of Colorado also makes window awnings like this as well and many people seem to like Carefree better than Dometic's A&E brand.
Best of luck to you.
