Inverter putting out 98 volts
I'm using a power line cigarette lighter plugin style inverter for inside the cab, running my computer and periodically, for a 32 inch tv for tailgating. I have never checked the voltage until today ...

If the tv works all is fine. Just the flat MSW registering low on the pear-to-peak voltmeter.
Get sine wave or a true RMS meter to read the volts.
It may also be an average responding voltmeter, rather than a peak responding one.
Most better MSW inverters are designed so that the peak voltage is roughly the same as for a sine wave (i.e. about 170 volts) and the duty cycle is such that the rms voltage, and hence power into a resistive load, is also the same. Often the peak voltage is none too well regulated so it's all somewhat approximate.
Assuming it's a modern TV, it's probably rated to work with a 100V nominal mains voltage anyhow. Many electronic devices have international power supplies that accept any voltage between 100V (used in Japan) and 240V nominal.
