I'll give the same reply that I wrote in your other post.
No, it's not a mess. There are areas of construction just like in the lower 48.
The area around Destruction Bay will never be smooth because of what the highway is built on. They have challenges up there with such a short season for doing repairs. We thoroughly enjoyed the trip and just took it slow and enjoyed the scenery. It's not an interstate.
We had absolutely no damage to the MH or toad on our full summer trip.
