This is a minor problem and I'm not complaining, but looking for a solution. After we reach our camping spot, no matter how long the drive, the drawer on the sofa is opened. The only thing stored in it is pillows and blankets for the sofa bed. Does anybody have an idea for correcting this? The rig is a 2008 bighorn that has never given us any problems what so ever, so like I said this is really minor and definitely not a complaint.
