I will probably not even have to look at a sales person again while dealing. In my town there just isn't the product that I want. Last deal was over the phone 300 miles away. Couldn't tell if he had all his teeth or coffee breath. :)
To the OP's question or rant, I totally agree with most you said. On our previous deal we had to deal with an ignorant sales person. But in all fairness I didn't know much either.
I always get a kick out of listening to sales people and newbie buyers at RV shows. some of the stuff that's being said is just hilarious. Or sad for the newbie that's listening.
