They make anything you want; just buy it.
Don't like high RPM? Buy an Ecoboost that packs in the air early so it makes early power and torque.
Don't like gasoline? Buy and Ecodiesel. It's a diesel so it's fairly low RPM but it makes low power but gets outstanding mileage.
Ecodiesel not enough truck or power? Buy one of the big 3 diesels. The Cummins makes torque at a very low RPM and the other 2 are right there also.
As far as RPM wearing out the engine. How long are you going to keep your truck? If you are going to keep your truck 3 or 400,000 miles I could see your point. Even then, most other stuff will be junk (window motors, HVAC systems, starters, interior, yada, yada, yada, long before that.) But that's not even close to the average on here.
