mac, I don't know - that makes as much sense as anything else I've heard. Maybe so.
LeBout, I don't know who the PO was. I bought it used from the before-mentioned big dealer in Western NC. It's just really weird - as if the factory installed the light and forgot to add the switch. Everything else in this TT is built well with no apparent shortcuts or omissions. I had pretty much given up on finding a switch, but having discovered this forum I thought I'd give it a go with you guys. At least they included the water heater switch and the plumbing to dump the black water.
