Dave, you have to ask yourself what you want to power with it?  Then you
can size it appropriately.  I would recommend a setup that we have done a
few times now.  2nd deep cycle battery under the driver's seat, then mount
the inverter right behind the seat.  You want to the run of wiring from the
battery to the inverter to me as short as possible.  Some of the new new
inverters have little digital displays for the remaining battery voltage,
and also sense when something is plugged in and needs power and turn
themselves on and off automatically (awesome!).  I have installed 1600 watt
units and they seem to do fine and would do most everything that you would
want.  Let me know if I can help you further.
