Anyone with a liftgate usually has a separate power cord weather a hot only or a hot and ground. Trying to charge batteries off a factory electric 7 pin is just stupid Liftgates draw alot of current. Best to have truck running when using it

30A is too small for that many batteries in any state of discharge.
