There's a State Campground in town. Water & Electric only, has a walk way over us 31 to the bay. It's called Traverse City State Park. I stayed there in July for the Cherry Festival. Back then I had a 28 ft 5th wheel. Don't know if they have a length limit? Here's their phone # 231-922-5270, or the call center is 1 800 447-2757.
