Shift level 3 and removal of torque management makes it hit gears pretty solid, but no one seems to have a higher failure rate for it.
I think they will keep within limits of what the equipment can handle. I have an aggressive tune set up, plus large tires and extra weight and crappy aerodynamics and the truck holds together just fine. Even slopping through hood deep mud holes and redlining up hills while the tires fligging dirt like a guy diggin out of prison.
I think you will be safe with whatever you think fits your needs.
