Yeah I've looked, either far away from me or the people want the brand new price for a used cooler. Nope. I can make it a few more weeks and keep looking.I had a yeti and somebody stole it out of my garage. Got an Rtic and it’s almost exactly the same and cheaper. I’d try Craig’s or an app, used to see ads where people magically had a surplus of them for sale
I'd rather just use ice, I can't see the lightweight battery playing nice with power being drawn when the car isn't on.If you’re going to commit to camping a lot, you should get a 12v refrigerator cooler, so while you’re driving to the track it keeping it colder. Just make sure the amperage isn’t more than the power point in the hatch can handle.
