Some of RV are being sold by individuals that might be very suspect in having various problems.
That maybe the reason they are not being sold through a dealer.
You usually have some recourse through a dealer that you don't have through a private party purchase.
While there may be some truth in that...I don't think this is normally the case.
There are probably more unscrupulous dealerships out there than there are shady private sellers of RV's.
One thing to keep in mind is that most RV dealerships don't offer up much (if any) warranty on a used RV and typically sell used RV's 'AS IS'.
I recently sold my 2015 5'ver by myself and sold it quickly, as where I live there are literally 1000's of RV's sitting around in peoples yards for sale and on RV dealership and consignment lots...and most of them have been sitting there in the same spot since we moved here a year and a half ago.
And they are sitting there unsold mostly for these two reasons...
1) The used RV's are almost always priced too high...
2) These dealerships and consignment lots mostly (but not all) are operated by the local RV dealerships...
In other words...the dealerships are using these over-priced used RV's to lure customers on their lots to actually get them to buy a brand new RV instead, that will bring in more profit than any used RV can.
I live in Yuma, Arizona and this place is an RV mecca!
There are so many used RV's all over town...everywhere you look there is an RV for sale!
While I could have sat on my 5'ver for months to years trying to get what it should have been able to sell for, I priced it to sell fast and got a fair price that I was happy with.
The new owner drove all the way down to Yuma from Idaho to look at it...and bought it two days after he originally called me from there.
I took the time to point out a couple of minor things about the RV because I actually knew about them as I was the one who used the 5'ver since it was brand new, where a dealership wouldn't know any of these things since they most likely just took it in on a trade towards a new RV.
Had my 5'ver been sitting on one of those lots for sale in the sea of other lonely orphaned RV's waiting to be claimed and losing their value each and every day...the dealership or consignment lot would have priced it high just like all of the other RV's sitting there and all the while the hot Arizona desert sun would have continued to take it's toll on the caulking, awning, plastic trim, roof vents, paint job and much more, which means that the longer it might sit there...the worse shape it would be in for the person who would want it.
Now...no more storage fees or insurance premiums...and I don't have to worry anymore about checking the caulking or taking the battery out to keep it from boiling over in the 115+ degree summer temps down here, or someone breaking into it or stealing it!
Used is used...be it a car, truck, motorcycle or a bricks and sticks house!
A used RV just needs to have a good and complete PDI done with the buyer and seller just as much as a brand new one does at a dealership before you take it off of their lot or out of their front yard.
Buying from a private party can save you lots of cash if you are looking for a used RV.
And if a warranty is the most important thing that an RV purchaser is looking for, then buying a brand new RV is the only way to go.
