Do the roads have overhead and side clearance for a large motorhome?

Yes! It will accommodate any rv.

I do believe so. I was there at night but did see several rvs. Big and small sizes of all. You may call ahead and ask for sure about your size of rv. Also google maps is also very helpful when trying to locate low overhangs and narrow roads and bridges.

We've been tent camping there many times and have seen RV's of all sizes at the various campgrounds throughout the park. You can call the park office during business hours with questions. The office staff is very helpful.

Thanks, very helpful!

Yes

pretty large clearings. I saw plenty of pushers there
