Can't determine without knowing what freq range the truck antenna is
"cut" for. There are two VHF bands, low-band VHF (49-108 MHz),
high-band VHF (169-216 MHz). Marine radios operate in the high band.

Generally it will receive ok but transmit range may be limited due to
high standing wave ratio (SWR).

Even a marine VHF antenna should be tweaked in terms of length to
minimize SWR in the middle of the radio's freq range.

I remember in the 'craze' the SWR meter was pretty popular, where you could tune a potentiometer to match the antennae to the radio for maximum efficiency.
