Truck salesmen are idiots

And if they had known the towing capacity and the payload rating, would you have immediately wrote a check or either vehicle, without at least checking to see if they were correct? You already have said the Toyota would be inadequate and that a 2500 Ram was too big, so even if both had been a Wikipedia of information, you still wouldn't have bought. Almost all people do their own research, decide what they want to buy and then go and buy it. The salesman's real job is to find the truck or car with the right options, in the right color and hopefully absorb the abuse that naturally occurs during the negotiation of price, trade values and financing. Maybe a good salesperson could point out something you haven't considered, but if the buyer has researched well, the salesperson is really just a face for the contact point between the buyer and the seller, not someone who actually is involved in determining what make and model vehicle you will actually buy.
