Batteries? Good call. A 4 year old Florida vehicle battery is on borrowed time, generally. Due to the heat. And your truck is sensitive to proper voltage.
I’ve been looking for replacements for my 2016. They’re getting a little slow and are original.
Generally OEM batteries (mopar, Delco, motorcraft) are good. Just saw Amazon has 850cca Delco AGM 94R batteries for $166. Seriously considering those.
Otherwise, Exide from Home Depot is a great value on the low end of the scale.
And if you want the best, get Odyssey AGM.
