Hi Dave
I would parallel them but I'd make sure that the voltage levels off
around 13.8 volts over the first few weeks.
Most maintainers will do that. Older trickle chargers often go too high
for continuous charging and optimum battery life.
Bob has posted lots of data on the ideal voltage over the years and
might have a better value than 13.8.

Constant trickle charging without a float charger is not wise. I suggest a BATTERY
MINDER they have a 1.5 amp model for about 50 bucks, I believe it may be
connected to batteries in parallel. However it will only maintain them. Such
a small charger will not recharge them if they are in a discharged state.
It will not over charge and also gives it a shot of high frequency energy once
each 5 seconds or so; which will keep lead sulfate from forming on the plates.
Sulfate is what eventually kills most lead acid batteries. The 1.5 amp model
is ideal for long term storage without harming a lead acid battery.
