We are currently looking at a used 2009 Rockwood Ultra Lite model 8319SS. This camper was stored inside a shop for 2 years unused. We did a thorough inspection and everything checked out perfect and overall condition was pristine. Our last item to test was the A/C. When we turned the fan on we noticed a small amount of while Styrofoam balls dropped out of the vents above. I inspected them and a few a had a yellow tinge with a slight odor to them. A couple mouse droppings came out as well. The seller said they will have the problem inspected and taken care of. My question is do I need to be worried of permanent damage to the anything from the mice? Do i need to be concerned about a permanent smell? I plan to be present when the RV shop does the inspection but overall I don't want to make a big purchase and walk into large issues due to this mouse issue. Any feedback would be appreciated!
