wolf packs would be closer to action packers than they are to pelican
the pelican are way tougher etc.. but also way more money and weight etc....
so for me I think I would pick wolf packs over action packers for storage of items that are going inside my rig/trailer
the wolf packs have great stacking and great use of space
the lids can be a bit funny to learn to take off since their are 4 latches on them but once learned not to bad
I think I would pick wolf packs over pelican to save weight and get great stack ability
if security and super toughness was my concern I would pick pelican(storm) cases
so if you had a combination of wolf packs and pelicans you could be set in my eyes
I really wish you could get wolf packs with a hinged lid on one side so the tops would not be loose
so if I was packing my rig up and I had 3 piles of packing solutions
action packers - pelican - wolf packs
I would pack my rig using wolf packs and pelican boxes and not bother with the action packers
I do have a action packer I throw junk in that is in my trailer so I have used all 3 but at the time nobody was bringing in the wolf packs ?
also the action packer fits the space just right so it works
hope that brain dump helps
