The bed ends will stay on the sail track (in the bags) when you are driving, but they will need to be secured to eliminate them flapping around.

These bed ends were previously made with a strap similar to seatbelt material, and Jayco found that they were deteriorating very quickly.

We now suggest if our customers choose to keep the bed flys attached to the van they modify the bag to connect directly to the van to prevent the fly from coming dislodged.

Some of our customers have previously put extra press studs on their bags to prevent them from sliding around.
