You've asked the right person, the Gleeful Glamper, as I have tried and obsessed, frankly, about many curtain and black out shade options. Of course, it has to look "pretty". Following are some photos of my, so far, best for me solutions.
To black out light I made manual roll-up shades out of Ron-Loc, black out fabric sold at most fabric stores and online. The rod is made of old tent rods which extend beyond the curtain rod brackets. Roll the shade behind the curtains. Note: the shade rods are not anchored and should be removed while traveling. I store the rolled up shades in the well under the front window, behind the sofa back in my 13' Scamp
For curtains I used the original curtain panels, or you could sew your own. I prefer my curtains to be 2x the width of the curtain rod for fullness. Other people prefer 1.5x. You can see in the photo that I also like to have side panels that I vary for decorative interest. I agree that the bottom of the curtain can be annoying when it hits your face while sleeping. I resolve that by running a tiny bungie cord with hooks on each end through the bottom hem/casing of the curtains. (these are sold by the yard at hardware stores) I attached a "cafe curtain rod hook" into the rat fur using an upholstery pin which corkscrews in. This has held up very well and allows me to open and close the curtains easily. I found I only needed to do this on the side windows. On the back window I slip a tent pole into the bottom hem and just let it hang. Since the back wall is mostly vertical that's all that is needed.
If you want further explanation you can PM (personal message) me or search "Gilda curtains" in the FGRV forum.
Good luck and have fun with this project!
