I live in my fifth wheel and wanted this not just for the great enclosed area, but also to help protect my awning from the wind. We've already had some windy days since we installed it, and allowing some air flow by opening panel zippers from the bottom helped a great deal. The one I received is all white - a nice surprise because white helps to keep my home cooler in the summer.
This is definitely a 2-person installation. A retired RV repairman helped me with mine. and the instructions made it pretty simple. The material thickness is very good and the zippers seem to be very good quality. The retired RV man has had two or three of these over the years and he gave me an excellent tip if you're going to leave it up all year. He said he learned the hard way on his first that the sun will eventually make the walls lose strength and allow them to become brittle, so he said to spray Rust-Oleum Leak Seal, clear, to the outside of the walls and it will protect it from the sun. It took several cans, but a small price to pay to extend the life of this product. He warned me to steer clear of other brands that are known to "yellow" over time. Over all, I would say this is an excellent Add A Room for the price.
