Forklift batteries for a solar trailer?

I have not considered running an A/C with it, as this is more of a campsite item, where multiple people in a camp would be using this, not just me. Where this will come in handy will be in cooler weather to power things like Keurig coffee makers, microwaves, and cooking appliances, this will provide the ability to actually cook on electric without the need for a noisy generator, and with enough panel capacity, especially with five days sitting unused in Texas.

Forklift batteries have not been mentioned, just because of the bulk. However, with my use for a camp at festivals where this is a static item, it just might be my ideal for what I'm looking for. Eventually, when I can get some acreage, it also might be able to handle power for a cabin with ease.
