installation went fairly well, I did it alone, a couple of old blankets help a lot I should say I'm 71. Cover had a small scratch probably due to rough handling by UPS. I live on a dirt road so I had to meet him a mile from home, corners of box could be reinforced.Overall am very happy with cover gets lots of looks and anythingauto gave me a great price! So far water proof!
