Had a problem lately, sometimes I would be turfing in LV and need to use RPG there then when I went to LS, I still had 17 RPG and I couldn't use them so I wanted to use MG for criminal events. Obviously I don't want to waste 17 RPG and shoot them anywhere just so I can get some minigun ammo.
So I am suggesting that players can store a maximum of 20 RPG only in their cars.
