Query: not durable

I purchased the Kar Pak carrier for use on a 3000 mile road trip. The tie downs did not last 1500 miles before the two in front began to rip out and I had to use a racheting tiedown to secure the load. I packed 7 sleeping bags and 2 tents in the bag and the bottom of the bag wore through in several small spots. I would return it but no longer posess the box or the reciept.
