We have the same model but a 2021.
With a single battery and the fridge, expect it to be running low by morning.
We picked up a second battery and that handles the fridge overnight usually at 50-60% state of charge by morning.
The 50w panel won't replace that so if you are stationary for multiple nights, plan to break out the generator in the morning to top up and the panel can do the last few %.
You will likely need around 150w of panels if you want to run the fridge. If you are also running the furnace and it's running a significant percentage of the time at least double that. This assumes you are judicious with other power consumption.
