We've bought A LOT stuff out-of-state.but only after after careful, aware research.
You have to be smart, astute, and unafraid in this area.
If you live in a rural or sparsely populated area (we prefer to stay far away from urban areas/folks) when the time comes for shopping for specialty/classic/rare items of ANY sort (including nice RVs) statistically, locally it's slim pick'ins and you have to cast the line "far and wide" which also requires travel, patience, and research and savvy smarts.
Retireds and folks with flexible work schedules have an edge here. Work-a-day folks are largely stuck time-wise.
Today's digital technologies allow sharing copious amounts of digital media including photos and videos of prospective RVs/trailers/vehicles. Yes photos can be deceptive, inaccurate, or faked/substituted. So buyer beware.
As other posters have recommended, leverage friends and relatives that may be near or within an hour or so of the sale-item-of-interest to put some human eyes/hands on it. I also like the recommendation on using a possible years old Google satellite view of a property, to see what condition it is in and if relevant, shop/storage buildings present. In our experience, generally an owner ether takes good care of all his/her stuff, or they do not - it's a life style choice.
The search is best supported by a holistic "all-source intelligence" (military) view of the situation, e.g. a property owner with a poorly maintained property, and without interior storage buildings, won't likely own/maintain, or be able to offer e.g. a pristine RV. Once visiting on-site, you can see a shop, tools, other vehicles etc. that may be indicative of a diligent owner, or a pile of neglected vehicles on blocks... and a likely scam. The ladies also tend to have a degree of "feminine intuition" if the sale doesn't feel/seem right walk away you're just out the fuel and time, and disappointment with in a fellow human.
As always be smart, act smart, and be fully aware. Assume little, verify. Look for inconsistencies. There are Eagle Scouts/Boy/Girl Scouts out there - just not enough of them...
Good luck - there are always gems to be found - you have to be the hard-working and energetic finder.
