I have this cover and purchased it for my 20/27 TrailManor. It fits perfect on the sides and has a small amount of excess in the front. It appears to be about the only thing out there that fits this size TrailManor. I have been very pleased with it so far (3 months) in the Florida rain and sun. Even though it has a longer warranty, I will be very happy to get anything over a year on it in this wicked climate. I have had no issues with it so far and it covers the A/C and hatch covers plus antenna without a problem. It's a good match for Florida with all of the rain and humidity. I needed something that would keep the trailer clean and allow the moisture to evaporate so as not to cause mold and mildew. So far so good!
