I’m off grid living in a camper cause I’m homeless

Soo I live in a camper trailer and I’m pretty much off the grid and independent when it comes to to my light source. I have a little eco flow river 2 it don’t last very long but I love it I don’t connect it to my shore power on my trailer but I have it connected to my LED lights I have and my tv and some fans if I wasn’t going to a financial hard ship and dealing with unemployment I would definitely get me a larger unit so I can power a AC during summer time and a heater during winter or be able to actually use my shore power connection. I have a 100w solar panel but I wish I was able to watch tv and not worry about it dieing so fast or have to worry about it draining so fast when night time come cause when there is no sun I’m screwed till morning. Anyway it’s a great product definitely helps and worth every cent just wish it was a larger unit and lasted a lot longer then mine does. Praying to god I may be the lucky one to win a bigger and better unit to support my needs at night
