Tree is correct - that would be effective.
I would like to add that for you and others that do not have
antennas for the VHF bands that you can still get on either with
the 5/8 wave 2m vertical that you can use on 6m and 2m or even
some very simple antennas - you don't have to have 10 elements or
more to work quite a few stations.
It does help to have the same polarization as the station you are
are trying to work. Most of the stations on the CW/SSB part of the band
are using horizontal antennas and you really need that too.
One way to do that is to put the 5/8 wave 2 meter mag mount
in a horizontal position - this will really work - the other is to build
a dipole or quad for 2m and 70cm. If you have a small 4 ele 2m yagi
those work great as well. From a good location you can do well with
these simple antennas. Since you are mobile you can usually move
to some really great locations.

One more point - for E-skip you can lave this antenna in it's
normal vertical position and it will work just fine since the polarization
is pretty random.
