Hi, Don't be gone too long! My van is on the way to being packed & if the weather holds (no snow... even though I have chains) and my plans don't change, I hope to be passing through Bend in 3-4 weeks (in my Westy)! I may be the one standing outside your door ;-) Have a good trip, and thanks for the electrical info. Learning something new each day :-) Cheers, Steve On 9/13/2011 9:19 AM, Rocket J Squirrel wrote: > Resistance /is/ resistance.
