"I will ride the shoulder if available to make room for passers"
----
Trying to be "nice" and let faster traffic pass, a friend did this "pull over far to the right" stuff until she caught a wheel on the shoulder and put her rig into the ditch.
Use all of your lane; if you don't, somebody else will! Pull over when it's *safe*, when you can see what's coming behind you and from the other direction, and when have *space* to pull back out into the lane. And, what happens if you're lane-sharing and the passer(s) don't have enough of your lane to get by before oncoming traffic smacks into them? Will they try to pull back or let you ram into a tree or go over the edge? There are many who do not care one whit if they force you off the road when you're "lane-sharing". Be aware of any traffic build-up and pull over when you can do so safely, of course, but endangering yourself, any passengers, and your rig just to allow followers to speed around you is a bad idea!
