We have been 34k in 8 months. We have a class B, but I can give you some specifics that you may find helpful.
PCH 1 around Big Sur. Going South, you would probably be fine. Going North, there are several blind curves that put you right up against the mt. I think the posted limit is 25 or 27ft. A 30 ft may make it, but you could just as easily end up run into the side of the mountain or run someone off the road by swinging over the yellow line. You can get off 1 and get on 101 for that piece. It is well posted. The rest of PCH 1 should not be an issue.
Sequoia National Park and hwy 198 have both 22 and 24 ft restrictions
Glacier National park Road to the Sun has a 21 ft restriction. This is to control traffic, not because of driving hazard. Going "around" takes about 1 1/2 -2 hours
Million Dollar Hwy and Beartooth Hwy have suggested limits, but 40+ do it all the time. You may have to slow way down to time your turn into some of the switchbacks
Iron Mountain Road in South Dakota have height and width restrictions. I do recall that anything over 30 ft would be a challenge in one of the one way tunnels because of the way you have to line up straight to get into the tunnel. If you had a day with little or no traffic, a longerRV might make it as long as the height and width are not an issue.
The Needles Hwy in Custer State Park, 25 ft is about the max because of the height/width of one of the tunnels. The line up for that tunnel is extremely tight and MANY people park their cars to take pictures of car coming thru. We had an issue in our 22 ft because of the tight run up to the very narrow tunnel.
Mt Washington Rd in NH is pretty much limited to cars.
Someone else will need to chime in on Moki in Utah
Most of the national parks have at least 1road that are listed "No Rv' s or trailers" These are generally side roads or roads the lead up to the mountain peaks, so you will need a toad or a tow vehicle for those.
You did not ask about camping in the national parks but it is something you may want to keep in mind...the parks were built before the large RVs were in fashion. So while all/most NP will have spaces for a 36 ft RV, they are not very plentiful so you need to plan accordingly and reserve spaces if you are traveling there during the summer months.
Also note: Height becomes an issue in some places in the north east
Happy Travels
