Well, the dealer doesn't know why the bags burst.
They said possibly due to the rough trail and possible defective bags. They replaced both under warranty and said to come pick it up. they said I shouldn't have anymore problems.
I hope not!
Hummie 2, thanks for the part numbers. I may change them out if this happens again. I will find a much closer trail and see what happens.
I have the same feeling about bad bags. I have been to Moab twoce this year and nothing happened there.
