We stayed at the KOA there last summer. It's nice and well kept. The owners are friendly and very helpful.
I wouldn't worry about the bridge. We have crossed it many times with a trailer. Worst time was with a 40 mph cross wind. They will then escort you at 20 mph or slower. No problems even in a cross wind.
