Charging ?
Is it okay to charge my trailer battery with a plain old car battery charger? I've never messed with a deep cycle battery before... Thanks.

David ... many times in your charging recommendation comments you unknowingly come real close to describing the long discontinued Parallax "T" line of RV converters. I sure wish I had one in our RV now!!
Every time that they were turned on, the Parallax T converters output 14.4 volts for 4 hours, then automatically dropped to 13.6 volts for the remainder of the time that they were left turned on. What this made possible was - whenever your batteries needed charging - just quickly turn off the converter and turn it back on so as to get 4 hours of higher voltage charging before the 13.6 volt output began for normal converter use in the RV, plus continued battery charging at the lower voltage. This line of converters of course also were available in various amperage ratings.
My AGM batteries would be perfect for a two-stage Parallax T charger in that they may be different than many AGMs - they like 14.X volts for boost charging and 13.5-13.8 volts for the remainder of charging and floating.
