Starts at the top. Marcus Lemonis (yes, that Marcus Lemonis from TV's The Profit) was a used car salesman at his great uncle's car lot in Miami. It was subsequently sold to AutoNation. Prior to that he ran for the Florida House of Representatives as a Democrat and was resoundingly beating by the 2 term Republican incumbent. After some wheeling and dealing at AutoNation, in '97 he and Lee Iacocca (yes, that Lee Iacocca) formed Holiday RV Superstores and then began acquiring distressed RV dealerships at rock bottom prices. In 2006 that company merged with Camping World and he managed to become CEO. In 2011 they bought Good Sam Enterprises, again with Lemonis naming himself CEO.
He (and Camping World et. al) have been sued numerous times for breach of contract, false representation, and internal fiduciary discrepancies. He positions himself as a philanthropist but he manages make sure he comes out on top when each of those organizations fold.
He is an unscrupulous businessman has no hesitation in selling shoddy products at top dollar and then not standing behind that low quality product. Not to mention other dubious business dealings.
There are a few utoob vid on depositions he's had to make after he's been sued. Personally, I wouldn't do any business with anything this guy is associated with.
But that's just me.
