As someone who often travels with a trailer I've been impressed with THIS waterproof and dustproof cover. Based on my observations, it is made from durable and high-quality materials that have kept my trailer clean and protected from harsh weather conditions .The elastic edges make it easy to secure onto the trailer and ensure a snug fit. However, the cover's design could be improved to provide easier access to the trailer's doors. Overall, it's a reliable investment for anyone who wants to protect their trailer..
