The USB will work as it's just a 5v regulator dropping down the 12-24v dc so it doesn't even go through the inverter itself.
As for the truck the 12v supply is probably current limited, that will depend on if it's fed by a drop down circuit or just attached to one battery (instead of the two batteries) If fed via a drop down circuit then there will never be enough power to feed the inverter as it'll be designed for simple charging phones/running satnavs and other low power equipment.

I'm not sure what the circuit is ,i have a suspicion it is fed by a separate connection on one of the 12v batteries as there is a separate cable coming off one battery that is not present on the other .There is only the internal lighting and the power supply that is 12V all the external lighting/ignition etc is 24V.The Hella socket (24V) is what would normally be used for running high power items such as TV's,kettles,fridges and microwaves but i would not have thought that charging a laptop would require that much power
