If I go into a camera shop, and ask the salesperson for a wide angle lens that will work with my Nikon camera... and he sells me something that doesn't... I can and will return that lens. I asked for something that will fit my camera, they sold me something that is not compatible.
I always hear that the consumer is responsible for what they buy... I agree, but the seller SHOULD also be responsible for what they sell the consumer. I'm tired of hearing that it's a business and they're there to make profit, etc... Of course they are... but for companies to hide behind that curtain and knowingly sell the customer something that they misrepresented, should be fraud.
Customer goes in, is this piece of merchandise compatible with my tow vehicle? This is my tow vehicle. Seller looks at tow vehicle. Yes, this trailer will work with your tow vehicle nicely. That is a lie, and should be treated as fraud. If the seller doesn't know or doesn't want to put themselves in that position, then they should inform the customer that they can't make that judgement and for the customer to verify with their tow vehicle manufacturer to obtain the specs, rather than fraudulently sell the customer something that is not what the customer asked for.
Yes, people should be responsible, but so should the dealers... especially with something as important as a trailer... a lens is one thing... but the wrong trailer can kill the customer and others. It's time business stop hiding behind the "they're there to make a profit" so we're not responsible if the customer kills himself when we knowingly sold him something that's not what he asked for.
Both are to blame here. But the customer was new and did not know... the dealer knows and has experience. They could've had the best interest of the customer's safety and made an appropriate sale, instead they hid behind the "make a profit" curtain again and put people in danger.
