Oh I thought it was a special "4 X" type of battery lol. Well from looking around slightly under 1000$ with free shipping of heavy batteries is probably a good deal for the right person.
And wow that's a lot of resources for batteries, thanks. You have a strong point about sams club. I've always wanted to buy one of those restaurant can's of tuna and mayonnaise from there and go to town!
I ended up going with interstate. If anyone reads this in the future and needs help finding a battery, there are a lot of stores that are also "interstate dealers" and they are everywhere if you look on their site.
I didn't think I'd end up spending so much but I'm looking at it as a months rv rent in california. I think I might end up getting a second 100 watt panel since it seems easy to install with adapters and I might as well spend my whole paycheck if I'm spending this much already lol.
I ordered two of these puppies, surprisingly only 10 miles from where I am
