I live in a VERY HOT and VERY WINDY area of the Sokal desert. I mention this to let you know that these cases are under VERY harsh conditions. I bought my first set of these covers for my 4X4. A Ford van covered with a special tarpaulin most of the time. He stands in the sun and in the wind. These cases (first set) are over three years old and still work great. I was expecting to change them every year as I deal with tarp/van covers but I'm happy to say they are fully functional. Even the straps survived! I just bought a second set for my Tacoma that is in the carport but gets some sun exposure at certain times of the year. I also assume that they will last for many years. I don't write many reviews but I had to say what a GREAT product this is. and great price! Many Thanks.
