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

I generally find one or two rv dealers selling parts and supplies. I go mostly to talk to the campgrounds as we do not buy a trailer every year, lol. Also it helps get you through the winter.

The one thing I don't care much for is when the rent spaces to people like bath fitters or basement water proofing. These should be at the home show and not the camping show.
