Perhaps the best "real way" is to plug the RV into a kill-a-watt meter and measure the consumption for 6 days. You won't be able to exceed a 15 amp (1800 watt) draw.

For each device like this I went to this website for a quick calculation: https://www.batterystuff.com/kb/tools/dc-to-ac-amperage-conversion-run-through-an-inverter.html

I'm so in need of some help here, lol. I cant wrap my head around it.
Thank you so much in advance for any info you can give me.

And I'd turn it into 12v DC - giving me the amp draw.
In the case of my laptop it was converted to 4.14a
I took those amps and multiplied it by how many hours a day I would use it.
The most I'd ever use it in one day would likely be 7hrs.
4.14a x 7hrs = 28.98a
So that tells me how many amps I'd use from that laptop a day, right? Am I doing it right so far? Lol.
