fridge lids

Does anyone else have trouble keeping the lid of their Engel on with out sliding it off? I don't know if it's the position on the drivers side in the back & sometimes too lazy to open the smaller rear door or if the wife & kids are just careless, but it seems to come off too often. Half the time I tend to stop on an angel which promotes this happening. Fed up with putting it back on at least once a trip, I've now put a cable tie on one hinge which is easily removeable. Works perfect, don't know why I didn't do it earlier.

Cheers
