We used this waterproof bag on a hitch carrier on our minivan for a trip from Maryland to Florida and back (about 2,000 miles). On the way down, we put everything in it that we thought it would hold, and it was only about 2/3 full. The straps tightened down to keep it all secure and prevent flapping around.
On the way back, we filled it up with bulky items to stay under the 350 lb hitch limit weight on our minivan. It kept everything nice and dry and clean all the way down and back.
We used a hitch extension, so we were able to open the rear hatch on the minivan with the full bag in place. It stayed in place well without any adjustments during the trip.
This bag is big! It blocked our tail lights on the minivan, so I used magnetic tow lights on the sides of the hitch carrier, and it was easy to overload it with weight. A heftier vehicle wouldn’t have any problems.
It looks like this bag will last for many more trips, but will purchase another one from Vevor when it’s time to replace it. Overall, we’re very happy with this purchase.
