My 2015 2500 4x4 regular cab just turned 204K with only issues being the typical broken exhaust manifold studs and rear carrier bearings but I have towed at least 100K with it. The 09 should be fine, if the price isn't too steep it should be a good truck... twocents

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
