Sounds like you're good with the clearance lights then.
I do have the original order sheet for mine. I'll see if I can find it and post it here. They blocked out the prices when they gave it to me, darn.
Mine has two 100 gallon fresh water tanks under the bed. A 75 gallon gray and I think 37 gallon black. Both of those tanks are mounted mid-ships left side. Mine had the Thetford toilet with the electric automatic flush thing. Just push the flush button and it does the whole thing electrically opening the valve and all. It wasn't always working well. Sometimes the flush valve would stay open. I'd have to fiddle with the buttons. I recently put in a Thetford with a foot pedal manual flush, no electric. Much happier with this one. Still porcelain bowl so seems pretty solid.
