Although my approach may be a little different, I too am looking into installing an autoformer and surge protector inside the coach - much like that described at
http://www.geocities.com/genieyorks/autoformer . Can someone tell me how the 240VAC is routed from the back of the coach up to the circuit breaker box on a 3400? I have looked inside the furnace cavity and under the stairs but do not see the cabling that I'm looking for.
Thanks,
Rick
