The cover fit after removing accessory rails that were factory installed on my pickup truck, clamps would not work on the rail edges, once rails were removed the cover worked as designed, much more frendly to use than the snap closures which could be painful in winter when cold outside, overall happy with my purchase.
The customer service was excellent, and the cover was quite easy to install. The instruction booklet was handy and easy to read. As of now I am very satisfied with my purchase and if I had it longer and experienced it's performance in bad weather I would have probably given it the 5th star. Very happy.
