In case anyone local to the Philadelphia area is interested, I have a nice inverter setup listed on Craigslist. Sorry, pick-up only due to size and weight.
Full 12v to 110v pure sine wave Sensata Dimensions 2400w inverter setup, perfect for use in a camper van. Includes inverter, Concorde (Lifeline) AGM battery, battery to inverter cables, and wiring to hookup to van alternator or battery for charging while driving.
