I'm getting ready to sell my Leprechaun 311FS and came across the website for RV Select (
https://rvselectinc.com/), an outfit based in Florida that seems to operate in about the same was as Carvana does: they buy your RV and take care of all the details & paperwork for you, then sell it on.
They seem to have a fairly good reputation. Of course, it's not hard to generate fake reviews.
I'd be curious to know, has anyone here dealt with them? Sold or bought through them?
