I agree with you 4x4ord but what's wrong with a gas engine running 3200rpm? Back before O/D was implemented not for towing or the faint of heart but instead for CAFE requirements, we used to run 3k~ rpm or more everywhere we went on the interstates. 3k rpm is nothing for those run forever 4cyl Hondas and Toyotas. My '98 12v 5spd/4.10 Cummins used to run 2500rpm at 70mph towing or not. 74mph was against the governor and that was all it could do. Didn't and won't hurt a thing. Higher rpm puts less stress on the engine, not more. Turbo chargers force more air into the engine increasing the compression ratio which makes more torque. That's a good thing. They also allow rpmaphobes to lug their engines when higher rpm would be better for the engine.
IDK how you figure we are "Lugging" or engines. For one, an auto transmission will not let it lug. At 74 MPH my little car engine is running 2000 RPM and I'm sure the new one are running less than that. My Cummins has been well over 100MPH and your old '95 would have too if tuned to do so. I think you need to go take you some rides in the new diesels but be careful, you might just have to walk out without your old gasser.
Have no doubt I would like a new Cummins Ram. But I need a truck that doesn't require down time for "issues" as I use my truck for work ~95% of the time. And it's not worth $8k to be able to tow at 30% lower rpm. I like the hot-rod sound so it's all good with me. The potential for horrendous repair bills is a turn off as well.
RPM at any speed is determined by gear ratio, not fuel type. You could gear yours to run at it's peak torque 1600rpm but you'd quickly realize the need for horsepower at the first hill where you'd need a lower overall gear ratio and "gasp" a downshift would occur. Odd thing is it would hurt absolutely nothing but to try to convince you of that is futile.
There was no "tuning" of the '95. I cranked out on the star wheel a few clicks to reduce turbo lag but other than replacing parts such as the fuel plate, fly weights and injectors, it's all mechanical. Even still, the 12v B Cummins was not going to run 3600 rpm without problems.
If I were going to buy one today, it would likely be this one.
