state parks with big motorhomes

About to purchase a Georgetown 379. Moving up from a 30 foot travel trailer. We adore state park camping and are planning a fairly epic round-the-country trip, but realize our ability to get in/out of them is about to change with the big boy. Is there a website/guide somewhere that's a compilation of state parks across the country that fit big rigs and have some hookups? Or is this wishful thinking (or a helluva project I should embark on?)???

No matter what they say or how they measure, we usually fit and find that there are always bigger coaches than what we have in most every one of them. What's funny is when they go by a wheel stop to the street, without consideration of the overhang behind the wheels and in which case we only require 30ft.
