This Thomas built freightliner bus has a Mercedes engine and a five speed Allison automatic. I have moved the door back so my co-driver can sit beside me and improve floor plan. Included is a mini split AC + heat pump. I have a 30 gallon water tank but no holding tanks, Bluetooth amp. amazing heater that runs on diesel, cell phone booster, microwave,need some finish paint job and cabinet work I found that I was not much of a carpenter. I have had a complete solar unit on the bus and have been camping and living in it without ever having to plug-in. I am amazed at the solar system that is fully programmable. The refrigerator is new and self-defrost and is amazingly efficient . I have a very efficient German water heater.The bus is in excellent running condition and has been maintained well. I just bought it from the school district last year while it was still hauling children at that time. They added new tires a service and two new batteries. I extended the back bumper about 18 inches making the bus about 33 feet long now. It will pull my 16 foot toy hauler without any problem. Fuel mileage is in the lower teens. I added a hot 100 gallon fuel tank for extended range and the heater also taps into it. It has a stove oven combination three burner,A double sink, water pump, shower and toilet combo, 30 gallon propane tank and a heavy duty reciver for towing. I have listed it as incomplete, still needs a lot of finish work but I am still working on it a little bit at a time and will send update pictures. It is registered and inspected and ready to drive away.
