The company I work for we have a total of 5 NVs. 3 are 2013. And they have over 400K. And they still run strong but last year they bought 2 2019 brand new and fuel pump went out on both of them. And the transmission on one of them every time u stop it clicks and then when you Go it clicks again. Sounds like the diferencial is messing up. I think the new NVs aren’t build strong like they used too
