Industrial vehicles like heavy duty trucks and also some tankers containing oil/water/milk that can be attatched to your truck would be pretty cool and also cargo ships and freighters that can carry anything by using some cargo containers by making 4 players carry the containers.
Industrial Items like containers of more stuff and also some other commonly used industrial items would be very cool.
I personally like your idea a lot, it would be very interesting for RolePlays, and even for singleplayer / multiplayer, as long as the containers attached to the trucks allow you to also store items.
It would be cool to see industrial vehicles in unturned. It would be interesting storing crates and items in the back of semi trucks and maybe disattach the trailer in the back.
This sounds interesting too, but wont work in singleplayer.
The solution is a forklift which is more efficient. Also it would work in singleplayer and multiplayer.
I personally think it is a cool idea! Would be cool if we have a military version of each of these things too! Maybe they can have multiple purposes, such as being used for farming and crafting?
