Store your money in a bag, on a roof, anywhere on the map!
I wish someone would make a mod that let's you store money anywhere you want, in a prop/model of our choosing, a bag, a pile of cash, or a big crate. That way we can come back to our hidden stash and take some money out of it and make use of it. So basically a mod just like "Dirty Money System" but without the hussle to convert it from dirty money to regular money.
A mod like that would add a whole new fun approach to the game.
@Itzhak880 Look man, it's a good idea, I'll add it to my list.
