271 Ah upgrade
I'm sitting in the camper now on our shakedown voyage with the new 271 Ah LifePo4 battery I built from 4 3.2 cells I bought from China. This is working out so well that I'm seriously considering build...

Everyones power needs is different. For me in the winter the furnace is the biggest draw and in the summer the fantastic fan is.
Currently I have a mere 136W of solar on the roof (actual ~100W output) and in the summer months my battery is full sometime between noon and 2PM.

How does eveything work in the winter when your running the furnace. I am trying to get an idea what these little camper furnaces draw in the winter. I am hoping to be aboe to get away with a 300watt pannel on the camper.

It is my understanding that the furnace draws ~4.8A while operating. How many AH it adds up to is dependent on outside temperature, thermostat setting and how long you have the furnace on.
Depending on where you live/camp solar is not very effective in the winter months.
My typical use pattern is leave for camping Friday afternoon and return noon-2pm on Sunday. While a single #27 FLA is good for overnight ether sometime Saturday night or Sunday morning the battery will be dangerously low. This is why I carry a EF1000is in the cab and run it for 1-2hrs on Saturday afternoon in the winter time to bring the battery back up.
With a 271AH battery I likely won't have to carry the generator anymore.
