I run 2 meters, 70 cm, and cellphone in my truck. I use a Comet
triplexer and a Comet dualband antenna. It's worked fine, but
I've never tried transmitting on all three bands at once. It's
very unlikely that the 70cm or cellphone will bother the 2 meter
receiver, but the 2 meter transmitter may bother the 70 cm receiver
and the 70 cm transmitter may bother the cellphone. I doubt you'll
see any actual damage, however. The triplexer I use gives me more
isolation than parallel separate antennas, so your problems may
be more severe.
Note that I'm using a dualband antenna for three bands. That's
not ideal, but it seems to perform well with the cellphone.
Comet does make a triband antenna, but it's a good bit taller.

You might add
Look for obvious cracks...the smaller ones would have to be
magnafluxed.
What is the galvanize like? Still good? corrosion?
I think I would be more concerned about the first 7 years than the
last 18. Sitting in a garage should not cause problems, as long as
the sections were not drven on, beat on, and in general abused.
Another thing you might inquire about is what was the size of the
antenna on top during the 7 years it was up. I think the 25G
could support about 2 sq. ft. or so self supporting, but Rohn
should be able to give you the answer.

Greg, those are good batteries for running HTs. You are only partially
charging them though. The terminal voltage of a fully charged lead-acid
cell should be 13.8 volts. This is only a "surface charge" that will
quickly drop to about 12.5 volts under load. What you want is a constant
voltage charger with current limiting. For slow charging, apply a voltage
of 13.8 volts to the battery. It can stay on charge indefinitely at that
voltage. For a more rapid and complete charge, use 14.5 volts and watch
the battery temperature. When it starts to get warm, drop to 13.8 volts
on the charger. Alternatively, a pulse charger can be used with voltage
sampling between pulses. When the battery terminal voltage reaches 13.8,
it's charged. Set the current limit so that you don't exceed the rated
0.88 A when the battery is first placed on charge. It'll draw more current
when it's terminal voltage is low. As the terminal voltage increases,
current draw will drop.
A lab power supply makes an adequate charger. I've used the little
Radio Shack lab supply for this purpose. One caveat, however, make
sure you use a diode between the supply and the battery. If you don't,
and the lab supply's AC power is interrupted for a moment, the battery
will blow the 723 regulator IC in the supply. Allow for the 0.6 volt
drop across the diode when setting charging voltage. I blew the regulator
ICs in both the Radio Shack supply and in an Astron supply before I
caught on to this problem. If you have something like a Systron-Donner,
Motorola, or HP lab supply, they're already reverse voltage protected.
Still, if you aren't sure, the diode is good insurance.
