Pretty close. In parts alone-- $1450 for the reman differential-- NOT installed, $200 for 5 gallons of 75W-140 synthetic gear oil, $190 for Transynd 668 Transmision fluid, $100 for trans filter kit, $225 for AC compressor, and $60 for Filter dryer, plus Freon, $1350 paid to driveline shop to redo u-joints and driveshaft, new AD9 air drier was $300, the two new Goodyear airbags were $160 each, and I either did this myself, or hired it done-- like rerouting the exhaust out the side-- and most of this stuff you can't see-- but it really needed doing to make sure the bus was as "road- ready"-- as possible...most of the time none of these things ever get brought up...
I have some 250watt solar panels, an MPPT solar charge controller, a never used propane instant hot water heater that I will throw in. I also have a virtually new Samlex 12 volt 3000 watt pure sine wave invertor (this thing is a beast-- on Amazon for $1225) that I will ad for an additional charge.
