Packed tents can make it so items can't be picked up that are under them. If a packed tent is thrown and lands upside down it can be very hard or not possible to pick it up.

I don't see how this would help base Arma at all. If this is for Altis Life, then they should mod it in instead of staying as a mission. That won't happen because they won't have the lazy masses if they required a mod download. That is the price you pay for supporting them instead of a superior modded version.
