We have a place in Menominee county on Big Cedar River out by 366 and 551. There is a "rustic" campground on 551 but I am not familiar with how it is situated for a motor home. Easy access to the trails which are very well marked. As noted, the trails are very dusty unless it rains the night before. Its a bit better in late fall. We rarely run into a bunch of traffic even on Holidays. You can open it up pretty good. Been stopped by the DNR twice. As long as you have your stickers and are not stupid drunk they are pretty understanding. But it is the DNR...
If you come up early in Mid-August a fun time is taking the trails to the Bark River Off-road truck races which you can drive to and park on-site. D-4 road off 366 is, IMO, one of the prettiest rides when the the colors are out. Too short at one mile long but well worth it. They keep threatening to extend the trail to the Island Casino in Harris but still not done yet. If you like to golf, IMO the casino has two of the nicest public golf courses you will play in Michigan, Sweetgrass and Sage Run. I believe you can stay right there with your Motorhome as well and you might be able to make it to 551 through the Indian Reservation and then down to the trails. A lot of asphalt on that trip though.
Here is a link to the Michigan ORV trails on the Michigan website. There are also a bunch of dirt roads you can venture off on like Westman Dam Rd. The area I am talking about is the South Beach (my term) area down in Menominee County. Only one trail there. Parking out by Cedar River and there is a pub there. Its not the geatest place but the beer is cold.

Enjoy your trip. We will be up over labor day finishing the pole barn. Maybe we will cross paths on the trails at one of the many "pit stops." Look for your license plate holder and a 🤙receiver hitch cover on a Blue '19 G2 with an old bald dude and a much better looking side kick. 🤙
Cheers!!
