Working on the electrical and plumbing systems is not much fun and takes time. You could not see progress of your work until you hookup the batteries, and that will happen not soon yet. For such small area it seems like a lot of wires. We pulled 250 feet of the electrical wire and had to order some more. It seems our bus will be very bright inside! We will have lights more than Christmas trees…porch light, entry light, stair light, whatever light, we got it all!
