oversized 60ft +towing a car

The average length doesn't matter, if you're too long. I've seen sites that could hold a semi pulling double and some that were too short for a Jeep Wrangler pulling a pop-up. Its more a matter of a space that's limited by an immovable object like a tree or the space between two roads. And that varies a lot.
I overnighted in a CG in Calgary, BC that had spots that were so long that they had full hookups at each end of every individual parking site. I've been asked the total length of my rig more than once.
That being said, 60ft. and towing a car will limit available spaces at almost any CG. There's no money in limiting the number of spaces in a CG to accommodate the rare rig that needs that much room.

There is nothing average about CG sites.

x2. we've been to places a 20' trailer is about the longest you can fit and others where the smallest site would handle my 60' overall w/o unhooking and plenty of spare room.

60 feet plus a car?
That would make you illegal in many states just driving down the road.
What is your total length?

42.73935 ft

Seriously, you'll have to check with each campground you might visit. The overviews on the Good Sam site will give you an idea. There are many that can handle your rig, but most can't. I stayed in two campgrounds owned by the same people and about 50 miles apart. Both said they could handle "Big Rigs". In one the largest space was a 45 feet long back-in site; in the other almost all the spaces were 90 foot pull-thru sites.

Where?

Older campgrounds, I've seen as short as 30 ft.

I've also seen as long as 100 ft
