bit of update. the seats are in, and the inverter is mounted.
power - Its mounted but im still working on the wiring of the inverter. lucky for me i found out NOT the hard way that both those solenoids above the drive in the bus are positive power. I guess the smaller one must be for the AC stuff. I thought being black wires it was negative but NOPE! So I took some old 1 gauge amp wire from a stereo and have wired for the inverter so it also goes through a 150 amp fuse (car stereo stuff again) and that way it will be FUSED... We played around with it last night and it tells me what volts are currently and then there is 3 sets of plugs that have their own fuses as pictured. With the bus sitting for a week now and using some lights etc the batteries are sitting a 12.2 volts which isnt bad for the amount they were sitting!
Also not shown because im too rushed and forgot to take pictures is that I have removed my front bus heater. I decided that where it is is where i want the fridge so it will go there. Lost about a gallon of coolant because it didnt work out how i wanted it to when cutting lines and putting the loop back fitting in... oh well .. partial coolant flush lol. I will have a nice fridge and possibly an AC unit for the drive! yeah!
