Tom,

The G5RV is a good antenna.  TVI could be an issue, of course, but and for
that reason, it is especially to get a good impedance match between your
feedline and antenna, keeping the SWR to an absolute minimum.  This is
always an objective, but in your situation, it becomes extremely important
to minimize TVI.  It will also be important to anchor the ends of your G5RV
as high as possible to avoid risking any liability issues if someone,
especially any kids, were to get their hands on the antenna while you were
on the air.  RF burns from a 100 watt PEP transmitter are usually not too
bad, but it doesn't take much these days for someone to file a law suit.
