I've installed chg-manual, and don't see any change.

I know it looks bad on the surface, however I know I can dump this
whole system up on 3 tapes and then the daily dumps won't be all
that large. So my plan is after seeing that the full dumps make it
to tape, I'll only stick a tape in the drive every week letting the
incremental dumps build up on /var/spool/amanda. Even though
tapecycle is 8 their are 12 tapes on the shelf. Does this make sense,
or am I out to lunch?

You mean diskdir? The path to the holding disk?
