Thank goodness there are those who buy new RVs. When we bought our current MH, we figured we saved about $30,000 in depreciation, because the coach was a year and a half old. Even so, it was like new, with less than 12,000 miles on the clock.
Neither the washer, dryer, microwave oven, dishwasher or shower (yes, even the shower) had ever been used. And consider this... At $3.50 a gallon, $30,000 buys 8571 gallons of diesel fuel, and averaging 7.2 MPG, we could take a 60,000 mile trip (Maybe break it up into a few trips

.)
My point is, RVs will depreciate by age alone. Their condition has (almost) nothing to do with it. RVs that are only a year or so old, are often in as good, or better, condition than a shiny new one, because all the bugs (or most of them) have probably been fixed. So, are you "crazy" for buying new? Well, no, but maybe a bit deranged.
