We tune in occasionally too. I just like looking at the units, kinda like going to an RV show but at home. The comments can be amusing, yes, I am sure the producers tell them exactly what to say and what to look at and everything. Some pretty dumb questions but remember its directed at new would be owners so they have to dumb it down.
I was at a show once and was looking at the suspension and tires and things that matter and have only had ONE salesman say to me that I looked like an experienced RVer. I asked questions that he at times was stummped about like on weights and acceptable tow vehicles. Newbies are really at the mercy of sales people and shows like this do not help in giving out the important information. That would just be boring now wouldn't it.
