beautiful interior, good job! I have a similar bus. 2005 e450 based. Its going to be a food truck, so my interior will be quite different. But, I am interested in propane and water tank placement. Also, on celling sides where the seat lights and air vents are. is there a procedure for properly removing? One more thing, from the inside it looks like you replaced the door opposite the drivers seat. was it originally a bi-fold door?
