Question About RV Shows? What's there and What's Not?

I was ta the Atlantic City RV show yesterday and saw the same thing. There was a 6' long table with a couple hoses , and misc small stuff but that's it. If I wanted to buy some gutter guards for my stick and brick, .... Or some wine , or some fudge I could... Heck , up at the Edison show I could have picked up some killer looking pickles , but no accesories....
