The RV shows
There is something for everyone at an RV show.  The shows at Harrisburg and at Tampa are two of the largest in the USA.  You'll find all the makes and models of RVs on display, travel trailers, motorhomes, conversion vans, pop-ups, and truck campers.  Plus RV accessories, campground information, and publications, and free seminars. 

You'll find RV shows in just about every state. Here are just two of the really big ones I've been truly impressed with:

Harrisburg RV Show

You'll find dixieland bands, clowns, plus free seminars led by Gaylord Maxwell and Sharlene Minshall; plus free overnight RV parking for hundreds of rigs (without hookups).  (717)774-3470.

Tampa RV Show
