The G5RV requires a tuner, this obviates trimming the antenna for any
portion of a band.

If you look at the total antenna system (feed line length and antenna
length) you will find that shorting the antenna and leaving the feedline
length alone will result in not being able to tune the high end of the band
on 75 meters using most commercially available tuners.

If you plot all frequencies betwee 3.5 and 30 Mc you will note a large hole
just above 4 Mc where no practical tuner can create a match.

I was looking through the G5RV instructions including the original article,
and it's clear the antenna, when it is 102 feet long, is tuned for the
bottom of the bands. Anyone have any experience trimming one down to
resonate in the mid part of the voice bands?
