Put this on the back of my '12 town and country. Got everything balanced evenly and bungee'd it all down, with a tarp and ratchet strap over it all. Traveled to the beach 70/80mph, all was well. I forgot to reverse the bolts as another reviewer suggested, but the type of cargo I had (cooler, chairs, bag of toys, etc) wasn't too delicate.
Assembling by hand was a bit of a challenge, the two primary bolts to attach the tray to the hitch/support bar were very tight. I'm sure anyone with a wider selection of tools wouldn't have had that problem.
I had to be careful though, turning into parking lots and such, to go in at an angle to avoid scraping the back. It seems that the bottom of the bolt sticking out (prob a good 1/2" past the nut) took the brunt of the impact. Another thing worth mentioning, as I have a row of sensors along the back bumper, the rim of the tray blinds a few of them, causing the system to disable (park assist sensors). The first time I backed up, it started screeching, then shut off and gave me a "Service Park Assist" message. Once I removed the tray and backed up where there was something to detect, it reset and took away the message.
The price is right and does the job. It would benefit from being able to fold up when not in use, and have a slightly higher rim (6"-8" would be very helpful), but for the price, it is more than acceptable. I will definitely pop this on when getting mulch and other dirty things that are not worth towing on the trailer.
One last thing to keep in mind when considering this purchase, if you are using it on a van or SUV with a liftgate, you will need to pack AFTER you have loaded the back, since your gate most likely will not clear your cargo. That was sortof a "Duh!" moment after I put it on. You may also consider tying some rags on the cargo where your gate may hit if it is accidentally opened when you are fully loaded.
