How To Control Dimension Text Placement

mstn V8i SS3

How can I control the placement of text in my dimension? Of course, once placed, it'd be great to be able to drag it where I want it, but the whole dimension moves.

See attached unacceptable result of using Dimension Element,  Dimension Size Perp-Line. These lines that are 3 ft. apart should have the dimension outside. The arrows should be outside, too.

Setting the text location to Outside in the dimension style editor dialog doesn't do a thing, as far as I can tell. Changing the orientation to Horizontal moves the arrows out, but with no lines (just the arrowhead), and the text text is still too big to fit with the two lines being dimensioned.

Is there some simple setting I am overlooking?
