I didn't find anything (yet)scheduled for Ohio and not sure where you're located but there is this one in Michigan.
6th Annual Vintage Camper Show and TCT Gathering
Date: July 24 - 27, 2014 Where: Port Crescent State Park, MI TCT Members and our RVs have been invited back once again to this beautiful state park! The park rangers go out of their way to accommodate us and our RVs' special needs. Our Saturday Open House and Tour is now a favorite activity for the locals and attracts visitors from 3 hours away! We entertain ourselves the other days with some legendary shenanigans - The Weiner Cookout, The Morning Coffee Klatches, Affagoto Time, Sunset Watching, Worst Tchothke Contest, Dancing, Strolling Singers, The Crock Pot Dinner and the Legendary and Entertaining Stir Fry. Spontaneous fun tends to happen as well! A few other surprises are in the planning stages. Host: Contact John Truitt at firstname.lastname@example.org, 313-701-8930 Follow this event on Facebook
Thanks...I did see that one. TNT also had a meet in Holly, Michigan which would be a lot closer but the email I sent for registration info came back as undeliverable. There wasn't much info on the meet but I checked out the campground's webpage and it looks like a nice campground. I think Ill try to contact the campground directly to see if they have any info.
