The engine battery if it starts the vehicle isn’t knackered usually, however if it has been left to go flat and is 4 years old ish, I would replace it as they have a habit of suddenly dying in the colder weather.
A heavily discharged habitation battery might pull more than 50 amps on an unregulated split charge so it wouldn’t surprise me if it was the cause if the engine was running, especially as you have 2 hab batteries.
If the van starts though, the starter battery should be good.
