4 minute video of our build - A 5x8 Camper for a family of 5 - http://youtu.be/CYGTlkfpIhY How we built a 5x8 camper for a family of 5, using a utility trailer with an incorporated bunk bed for the kids. From plain trailer to campground! Also - More pictures here: http://flic.kr/ps/225piC
I've used 18 of them, in a variety of sizes 12x18 to 15x24. Great windows...and, like mentioned, the nice thing is that they can be open in a rain, unlike a slider. Doug
