I have just read above when this question seemed reasonable. You're naming some electronics that seem to indicate heavy electric usage. So what do you estimate your amp draw will be ? Lets just start out with a test drive on that number. You might be reading into my post and know where I'am headed.
There are some really sharp members on POG with electric use knowledge way beyond my pay grade. I'am suggesting you should consider this topic as we all know how far 50 amps go on each leg.
