Your truck doesn’t directly supply the “power” when driving, and unless you’ve done considerable charging modifications, it supplies only a very low amp charge to your trailer battery if everything works Ike it should.
Not even close to what the inverter pulls off the battery to keep the fridge going in the dead of summer. Maybe winter too.
Now if you only drive a couple/few hours between being plugged into shore power and plugging into shore power again, yes you can continue getting by with a little single battery.
But do/will you ever drive all day long, maybe have a 24hour lapse in shore power? If so your setup even with a bigger battery won’t cut it.
I only mention this because the battery(s) are the biggest part of the equation you mention and if it’s time to get a new battery, it’s the best time to think about whether what you have will continue to work well for what you need.
