Puschasing a Class A with Manufacturer Full Warranty

If there ever was such a company, dumb enough to warranty other manufacturers products on their nickel; they'd be bankrupt & out of business by now.
when you buy a house on wheels, you're buying a dozen products from a dozen different manufacturers.
PS: your car mfg doesn't warranty the tires that they didn't manufacture, they make you go to the tire mfg.
