A camping forum for VW bus and camper owners.
No I bought the exact same 1100w inverter they sell at Go Westy but got it through Sears and saved a bundle since I live in Maui and we have a Sears it worked out much better. The Go Westy kit re wires the sink, 12v on dash, radio, interior lights, and clock. As far as the charger this is a 3rd vehicle only for surfing and beach time though the guys at go westy said since I am not camping more than a few days at a time I am best to just buy a battery charger and top it off (aux battery)overnight and I will be more than fine.
As far as installations my confidence level outweighs my ability but this was very easy and am eager to do more plus they answer a million questions for me without hesitation.
