You do not want a regular SLI (starting, lighting, ignition) battery.
They are intended for large peak draw, but not deep discharge, and
will be damaged by repeated discharge.  Pulling a car up the ramp is a
deeper discharge than the design goal, probably.

I'd use a deep cycle battery.  Also, cnsider some sort of battery
tender for the battery, to use when the trailer is parked (which I'm
assuming is most of the time.)
