I watch my temps, especially when it's 95+ degrees out and running on the highway I'm around 205 degrees. In traffic, I've seen at most, 215-220 degrees, sitting at a light, and that always drops back to the 205-210 range when I get moving again, then when up to cruising speed, it's back to around 205 degrees. I do understand what you're alluding to but, this has been working very well for me <knocks on wood>You'd be running some high cylinder pressures and making more heat doing that. Very inefficient. You are fording it to stay in low lift valve mode and in the low torque and HP ranges.
I only manually shift if the transmission is "hunting" - otherwise I let 'er rip.
It runs cool and gets nearly 14 mpg, even in the hills on I80 between Altoona and Iowa City where the big rigs keep shifting to keep up speed.
Seriously not good to keep the RPM low - and it makes no sense, really. Heat rejection is in a bad place at those low RPMs under that sort of load.
I can never recommend keeping below 3,000 while towing and trying hard to stay in the low 2000s. Just not good.
