4,000 - 4,200 RPM?
I have a 2004 Chevrolet 2500HD with the 6.0 and 4.10 rear with about 80,000 miles on it. This is what I use to pull my 8,000# travel trailer. I have kept it well-maintained and it still seems to wor...

You're putting more stress on you motor by trying to make more HP down low than by winding it up.
Cylinder pressures go sky high at wide open throttle at low RPM as apposed to WOT at a higher RPM.
Here is a good chart to look at.
If you want to get the most from you engine (such as climbing a hill) you need to be around 4,000 to 4,500 RPM looking at the chart.
I don't know where all of this RPM phobia comes from? I wind up a 572 big block all the time to 6,800 RPM. That is an engine with huge heavy parts. It can live at that RPM all day long even though I would hate to pay for the fuel it would use making that kind of power. BTW, modern tachs don't have red lines on them anymore. Wonder why? In the old day when you had an all mechanical engine you could over rev the engine and blow it up. Now days with modern electronic controls and computers that is impossible. You can take a modern truck in neutral and hold the accelerator to the floor. :E And no, nothing bad will happen because of modern rev limiting and engine controls.
As far as wear on the engine. Yes there will be more wear, but it will be so negligible it's not even worth talking about. If treated right most modern engines will outlast the vehicles they live in. I get a kick out of people that say, "my Cummins engine will last 500,000 miles and your brand X won't." LOL, that may be true but it would take me 50 years to get to 500K on my truck.
One thing you will use more of is fuel. The more RPM you use, the more airflow through the engine you will have. The more airflow through the engine the more fuel you will need with it because you are now making more HP.
Think of your right foot as a fuel and HP regulator. Want more HP? Press harder. Want better fuel mileage? Press lighter. It really is that simple.
