We have had many request to raise the storage capacity. I actually disagree with the fact to raise the container amount. If one is scavenging, you are able to carry the left over boxes with you which defeats the purpose of increasing the capacity. However some people are displeased with it still and perhaps a different compromise can be made. We may need to increase the rarity value of some items to increase sales price? We still need an "estimated time remaining" on the loot boxes to give use a general idea on which boxes to keep. This is another compromise that can be made as a makeshift capacity limit.
I am not in favor for increasing the limit, but am willing to provide technique for better scavenging.
