<html><div style='background-color:'><DIV>I also use a small window AC in my westy, but only while camping.&nbsp; It mounts in the drivers window.&nbsp; I think you have overlooked a major problem in trying to use the unit while operating...power.&nbsp; Though the inverter is heavy enough to handle the A/C, you can't supply enough 12 volts to the battery/inverter to keep the battery charged, not to speak of running the van itself, plus lights, radio, etc.&nbsp; If the A/C pulls 10 Amps at 120V, that's 1200 Watts.&nbsp; Assume 75% effeciency on the inverter (that's optimistic) and you'll find energy useage of 1500W.&nbsp; A 70 Amp Vanagon alternator at 12 volts supplies a maximum of 840W, barely half of what you need just for the A/C.&nbsp; Where is the rest of the power coming from?&nbsp; If you are depending on the battery to supply it, you'll be in a dead battery state very shortly, not to speak of decreased altermator life while running it full tilt for extended lengths of time.&nbsp; The power just isn't there...run the numbers.</DIV>
