I have one of these in my receiver hitch.
I've used it several times, and it works great.

I'm assuming that you mean is it safe for your truck to be in reverse gear when pulling someone out, correct? Yes, it is, since Nissan put a tow hook in the front of the truck. Just make sure that you secure the strap to a tow point, axle or frame on the vehicle you're pulling out, and go slow.
