Scott,
My suggestion would be you do something different.
You will have much poorer efficiency with a vertical dipole
of loaded elements compared to a similar height and coil
style antenna worked as a Marconi against a good ground
system.
If you can, you might consider as large a ground system as
you can muster (as many straight radials as you can fit, or
a screen) and a Marconi antenna. You will have less ground
loss, less feedline radiation, wider bandwidth, and better
antenna efficiency if you keep the same overall height and
use the antenna as a Marconi. The only thing you have to do
that is more work is install a ground of some type.
A vertical dipole is workable, but decoupling the feedline
is a chore and the losses are pretty high with two mobile
antennas back-to-back.
