How many of us are there? Owners of Dodge based RV's?

I have been printing the information off to reference later... Good info.

I finally had a chance to do a little testing on my DC problem, and have narrowed it down to one wire. Unfortunately, the 'hot' seems to have shorted out somewhere.... Dang it. There is maybe a foot of it visible before it disappears into the wall and routing to the opposite corner of the RV. Taking suggestions as to what might be the best way to get a new wire to the destination. Anyone with experience with this?
