I agree with kd, Gary, Steve and Pug.
The ads claim how strong their trucks CAN BE, and how much SOME of their trucks can tow. They ignore the fact that VERY FEW of their trucks live up to that standard. Ram has a unique grill on their top trim Limited model, which is almost always the one in the commercial. The truck you see (Limited) will NOT meet ANY of those specs they claim!!
Trucks are touted as tough vehicles that can do anything. Salesmen do little to dispute the idea. Many do not know the trucks real limits, and do not want to know. They want to sell trucks. Many RV salesmen are as bad.
While it would be tough to identify outright lies in the ads (there is always unreadable small print) it is certainly a case of misinformation and misrepresentation.
Short of federal intervention, I doubt anything will change, and the truck industry has VERY well funded lobbyists.
