You're getting some great advice here. As you pointed out, salesman are not necessarily the most informed.
Take the fact you learned that, and apply it to your choice of tow vehicle as well. Don't rely on the salesman to quote you the gross towing numbers. You need to focus on cargo capacity for your tow vehicle.
Figure 13 percent of the trailers GVWR will be tongue weight. That, plus the weight of your family, weight of everything you add into the truck should not exceed the cargo capacity specified on the yellow sticker on your drivers door or door jamb.
What happened to the E350?
