Yeah, the price difference between RVTrader & Preroamed I think tells a story. Ordinarily we all would consider dealer pricing to be the more expensive option for used....and with it you get a certain amount of reassurance (IE, the ER has gone through the vehicle & double checked everything). But there seems to be a certain "pride" of ownership for these private party prices.
...also people don't appear to actually drive these things
I met a guy at an early OvEx, ahh, maybe 10 or 11 years ago now who fit that mould for sure. He was selling an F-550 based mega-camper from one of the big upfitters, for 70k less than he paid for it. Keep in mind, this is before the "over land" explosion and massive inflation. Rough numbers, if I recall, were in the mid 300s, when new, and he was asking 270k. The truck had 7k miles on the clock. I asked why he was selling and why the mileage was so low.
"My wife and I visited Yellowstone, Glacier NP and the Grand Tetons and now we don't need the truck any more so we are selling it."
This guy does not work hard enough for his money, obviously. He basically took a $70,000 vacation. For that money, you could hire a limo to take you to all of those places, rent kayaks, mountain bikes and any other gear you want, go heli-skiing or take helicopter tours, hire a private guide or chef and have LOTS of money left over. The idea of buying this truck to drive to three national parks that you could visit in a 30 year old Toyota Camry, is simply absurd and ridiculous, at best.
