Great for the price
For the price, this is a great cover with plenty of useful features. It's worth noting that many reviews note that with the Utilitrac system this works but limits your use of the bed extender. That is very true as the adapters that hold the rear section of the cover on fall right where the bed extender normally rests if you use it as intended, meaning you have to move the extender up into the bed further, slightly diminishing its usefulness. Probably worth it for dry storage space, though.
Utili Track install tip
Very pleased with the cover and would recommend it to others. My Frontier has the utili track system and this caused a small problem at first during installation. It made placing and holding the clamps behind the brackets difficult. I found that I could lightly tape the clamp on top of the track, set the bracket, and tread the bolt. Once nearly tightened, I pulled tape out and finished off the job. All of the other clamps installed quickly.
