What is the max amp output on your charger? For my 2 6v GC batteries I charge at 40 amps, when batteries are 50% depleted. You can buy a portable 40 amp charger for about $100 or so. Depending how your trailer is wired, and the age of the trailer most will draw from the battery when plugged into shore power and the battery acts like a filter. When you are plugged into shore power check the voltage at your batteries you may already have a built in charger. If so your voltage should read 13 volts plus. Most trailers and MH's have a built in charger. Maybe someone on here is more familiar with your trailer and give you a more detailed answer.
