Hi,
As for your inverter install, I like it a lot. When I did the homework on the distance to the inverter in the cargo area(like yours), I was advised not to do this because of the voltage drop to the rear of the FJ...they say the cable lengths are too long(13ft one way), and this reduces the effectiveness/use of the inverter...(Don Rowe company/experts)
Have you seen power limitations? I know your is 1000W, I am thinking 1500W...
what cable gauge did you use? They say if its too small, it will heat up...and pose a hazard...
any help would be great.
Mike
