I decided to keep it. I bought a back seat cover ( including head rest covers) that I will install in addition to the hammock. We will see how it works. As there are metal rings along the hammock edge, I will be able to use bungees if the cheap plastic hooks end up breaking. I have looked at other options (including cabela) but in addition to being more expensive, most did not have openings that are necessary to use the seat belts (for the safety harness).
