40' Length Motorhome to big for most campground's?

I've only been in a few, owning my 36' coach for less than a year, but so far I've found that most every campground we have looked at can accommodate big rigs with 60'-80' pull-through or back-in sites...... BUT.... you might have trouble conveying through the campground to get to those lots due to trees and other fixed obstructions that the owners didn't account for. At our local lake, a state park, it is a fun test of your driving skills to get to the bigger sites down near the water. But it CAN be done.
