you can gat one heck of an invert for 2k
and have it installed
go shp around and then find a reputable place to install it if your unelectrical friendly
west marine has great ones that are rugged for rv use
i have a 1750 watt in my truck hard installed and it has been beat to death and still keeps on ticking
best to figure what your load will be then the batteries to run the inverter and f course the recharge on the batteries
i hate to keep saying west marine.... but thier website and book will lay it out based on load and batteries.
easy as falling off a log
