There’s like 4 different tiers, covering from basic powertrain up to everything but wear parts. I haven’t checked in the last year or so, but these two dealers had great pricing on them. It is basically an extension of the factory warranty. If you want to do an extended warranty, these seem to be the best. There’s probably a few others. I’d search around if you are interested, but you’ll do way better than buying it at the dealer who you are buying the truck from.
