I have purchased different travel trailer covers however, the Classic Accessories cover provides the best value of all that I have had. I purchased a cover for 22'-24' travel trailers and it does fit my 24' trailer perfectly.The amenities that I appreciate the most are: There are full length zippers on the back two corners, the right front corner, and two zippers down the right side of the cover where the trailer doors are located. With these zippers, the two doors in my trailer can easily be accessed and when it is time to remove or reinstall the covers, these zippers make it very easy to perform and removal and installation. Further, there are screened vents along both sides between the sides and the top and these vents are covered by a flap that protects these vents from rain, snow, etc.This is my second cover. The first cover lasted 2 1/2 years and the reason I replaced the cover is that the front began to disintegrate due to exposure to the sun. This exposure lasts approximately 10 hours per day during the summer. Without this exposure, I would expect the cover yo last much longer.
