A friend and I were discussing this and he suggested:
From Tyler Bend, I don't think there are any campgrounds like he needs. He needs to look at one of the Maumees down to Buffalo Point where they have showers, hot air blowers and nice bathrooms. If he wants another day, he can start at Buffalo Point and go down to Rush the second day.
I suppose he could go upriver from Tyler Bend and camp at Tyler Bend, but I've never paddled that stretch or camped there. It is very close to Highway 65. Buffalo Point is more secluded, although it is perhaps the most used campground on the river.
