New(er) Dodge aka Ram trucks.

Totally get it, its bot for everyone and yes the cost for repairs is higher. Please don't get me wrong the 6.4 is a strong hemi.
I have never had any issues with running out of power with the 6.4, it just fit my needs better.
It sits most of its life, I bought it new, just turned over 25K miles in 7 years, so I most likely will never wear it out.
Heck I only put 1500 miles on it last year.
It just gets used for truck stuff, not daily driving.
