Family campground recommendations in Southern MI, IN, and Western OH

[Jefster]

I'm traveling to visit family next week, and I'm thinking of taking some extra time to camp on the way down and the way back. It's a bit last minute, so state parks are probably out of the question. I'm also pulling a 36' trailer, so need something with big enough sites.
Any family campground recommendations in MI, IN, OH? I'm fairly familiar with MI and I have a few favorites there already, and we're possibly thinking the big Jellystone in Northern IN for a couple nights, but I need a few other ideas for while we're on our way from West Mighigan to Southern OH (Cincinnati area)

We like Delaware State Park, Alum Creek State Park, and Findley State Park in Ohio. Findley probably a bit out of the way but the other two are nicer imo anyways.

Probably too little too late as it seems your trip has passed, but we frequent Jellystone in South Haven, MI. Great campground, but even better is the proximity to some great towns, beaches, and breweries!

East Harbor State Park is a nice place to camp also. Right by Lake Erie.
