In addition; a couple of options to SWC shades are:
1. MCD out of Texas
mcdinnovations.com a bit more costly but very high quality, custom made, with great customer support.
2. Levolore makes pleated shades at about 2/3 rds the cost of SWC. You can get them a Lowe's. They cut them to width right at the store while you wait, work well in a motorhome, easy to put up and come in several colors and light transmission - either black out or some light, but it's a single shade so it's either black or some light.
