Mild Rant. Don't Any of You Take care of your RV?

I believe Rv's are a lot like Exercise equipment...
You buy it cause it seemed like a good idea, use it for a couple of weeks, then hang your laundry on it until you sell it.:S
My trusted Rv mechanic says a 10 year old rig with 10k miles is more likely to have problems than the same rig with 70k miles
