I've done this. Here are my tips.
Yes, it can be charged from the tow vehicle, use a switched circuit to
do the charging. I can't tell you about the 4 wire terminal, my
vehicle uses the LARGE round plug, (7-8 wires? Plenty there to find
one to use for charging).
If the trailer will be sitting for extended periods you need to
maintain the battery charge, or use a RV battery.
