FYI my cargobob was before patch 1.07, got it using the lag switch sp/mp method. I was expecting it to go with this new patch, I bet it will next one though thanks to this method haha, enjoy it while you can.
Regarding Bust Out, yeah spose it wouldn't work to steal the bus. Would be interesting to see if you lined it up right, if the momentum of the bus suddenly catching the lifting hook would rip your chopper into the ground. Gonna have to try that now
It's no use calling it in for Coveted.. You would be shot down before hooking on or too damaged to get away. And by the time you cleared the area, the mission Bob would arrive anyway.
Also, there's a mission from Trevor where you have to steal a trailer, the mission is up on top of a hill, the trailer is inside a fenced off area of some kind. I used the Bob to steal the trailer after killing everyone, it just took the trailer not the truck. When I dropped it off, it wouldn't register as me having retrieved it, it needed to be hooked on to a truck. So I flew back but fcked up trying to get the truck and blew it up along with myself so I just did it the normal way.
Not sure if the same would happen to those other missions that require you to steal a trailer, where the game assumes you will need a truck.
