On August 7 our 2005 Itasca Meridian experienced a short in the main ac wire bundle just aft of the shore power line attach point (aft of the left rear wheels). The fire occurred about 1:20 in the afternoon while we were out for the afternoon, and thanks to Good Samaritans in the park the fire was extinguished before the fire department arrived. Unfortunately, 90-95% of the smoke went up through the bed housing (through a 6 inch square hole in the floor- through which wires passed) and thoroughly coated EVERYTHING in the coach and killing our dog.
The fire department tried valiantly to resuscitate our dog to no avail. Absolutely everything in the coach, even in closed drawers behind doors (as in the bathroom) was completely coated with a black, oily and highly toxic residue. The fire chief on the scene warned us to wear masks when entering the coach to retrieve personal belongings we thought we could salvage. Everything below the main floor (as in the basement) was OK, but the entire bedroom was completely water soaked as well as smoke filled. The Fire Marshal removed a covering of the main electrical distribution area inside the shore power compartment and found that an ac power line had rubbed on a 90 degree sheet metal corner and finally worn the insulation off creating a short which started the fire.
I would advise anyone owning an Itasca made during this era to remove the covering (nominally 6 screws) and check the wire harness for chaffing and mitigate any potential rubbing of wire and sheet metal.
