2006 Ford E-450 shuttle bus

This is an E-450 ford bus I bought from the city to convert into a camper was a very fun project that still needs a little work I am selling because I am required to move into the dorms for next year of college the bus runs well the only problem being the dash lights do not work so its hard to see the speed at night and the float on the fuel gauge is off so I go based on millage. Im asking 11k obo

It has a 24 volt solar system missing one solar panel has 4 100amp hour batteries charger controller and 24 volt 6000 watt pure sine wave inverter

Water system needs new fittings as they do suck air but has fresh and gray water tanks with a pump ready to go once fittings are changed
