Question about running a carfax report on an rv.

I recently traded a vehicle for a new one and yesterday saw my old one listed for sale by the dealer. Out of curiosity, I checked their website and it said they had Carfax on my old vehicle. Having never used Carfax, I was curious as to what it said.

The Carfax wasn't even right on what city I bought it in! It didn't show an accident last year ($9500), nor did it show the routine factory scheduled maintenance performed at the dealership. All it showed was oil changes.

So much for Carfax innacuracies!
