This is my second priority start that I bought. My 2015 work truck battery is dead at the end when I get back from vacation. So I bought one of these. My parents' 2017 plow regularly idles and the battery dies, so I put one on their truck. Since then, my work truck has never let me down and I no longer change the battery every 18 months. I hope my parents love theirs as much as I love mine! Follow the instructions and it's easy to install. The hardest part is finding a good place to install it.
