If I'm driving, we have zero problems. OTOH, if DW is driving I open the door really slow...:E. Really, it depends on how you drive. Low and slow is good. Hard and fast, not so much. We still use the bungee on the door and it works well. Only on rare occasions have we had anything spill. Some things will tip over or move around, that's to be expected. Just remember when you get where you're going to open the door cautiously. Even the best 'solution' could result in tip overs with a hard stop. You won't have to worry about jack rabbit starts...:B....Dennis
