Differential swap
Our tow vehicle is a 2004 f350 with the v10 and 3.73 gears. It pulls just fine here in flat-land country, but not much of a grade is needed to make it shift down. We'll be heading out West in the near...

If your truck was turning 2100RPM at 65MPH in OD with the 3.73 gears, it will be turning about 2600RPM with the 4.56 gears.
That's pretty close to just shifting down a full gear in the transmission, and you have to listen to that all the time now, when you're not towing. It's still going to shift and when it does, you're going to have a conniption fit, because it's really going to roar. My estimate is about 3600RPMs in direct at 65MPH.
If it was purely the shifting that bothered you, this might work out, but for most people, it's the RPMs that make them uncomfortable.
