Not sure about Michigan, but here in NC the state parks are usually very nice and very accommodating to our Class A. In some places, there may be a few trees in the way of making turns, but a little scouting will keep you out of trouble. We love to sit outside under our canopies and almost always have a fantastic view of either the lake, beach or the mountains. The state parks here have 50amp service on select sites and typically have water to each site. Haven't seen one yet that has on-site sewer, but they all have a dump station at the exit to the campground. We found one solution to let us stay put longer is an outdoor shower. We have a portable water heater that hangs in a collapsible tent/shelter. Grey water tank is no longer an issue and if the two of us fill up the 35 gallon black tank in a week, we BOTH need to go to the doctor! LOL!
