Length restricted rv parks

RV parks, called or advertised as such? Offhand I can't think of many, if any, that I have personally run across. Possibly the Goldrush campground in Dawson City would have to turn away such RVs due to space constraints, but I don't know that for sure and their web site makes no such statement.

Campgrounds and state parks? There it's rather more common. There are at least one or two Vermont state park campgrounds that I cannot use with my 32' motorhome (and that's ignoring those that are hike-in/walk-in only). There are quite a few more where only a small handful of the sites are suitable for larger RVs.

Most newer commercial RV parks have at least some sites 40+ will fit. Although they may not always have a site available when you need it. Older RV parks and national/state//city/COE parks it is far more iffy. You can likely always find something. It just may not be where or what you would like.

We have run into it a few/several times but I can't cite who they were right now.
We have stayed at some that should have been restricted, crowding out into the road.
Most are much older parks that still have not updated with hookups on the wrong sides many times. State parks use to be and COE, we have encountered when looking for possible rv parks to visit for fishing etc. All this is subject to, and has possibly changed now.
Canadian parks some are limited, with clear indications they wish those with Mhs to stay in commercial parks. A clear bias against (rich) Americans, with big Mhs aking up spaces that Canadians with smaller units still exists.

I’m 43 feet tip to tail but with a TT articulated after the first 17 feet and there are still some campgrounds I can’t use. Therefore, no 40 foot MHs for me. I want to see or re-see this great country.

None that can think of. We've hit all the lower 48.

A huge percentage of the RV parks out there were built years ago before the gargantuan RVs of today were ever thought about and so they aren't able to provide the space needed for them. Any good RV directory will show the maximum length permitted but it would still be nice to call ahead if you're wanting a space before you pull in only to be disappointed.

Something I've seen occasionally are parks that have SITES for my 40', but the access lanes aren't designed for it. Most noticeably, those parks where you have the long rows of sites with 180 turns at the end, but trees everywhere. Mostly happens in the state/federal parks or older parks that were designed in the 50s/60s for smaller RVs.

I have not seen any parks advertise a length limitation but if you look at the site there may not be any that are empty that will fit a rig of that size. They may have one or two but you may also never be able to get one of those. There is a Michigan State Park that has 5 sites that are good for 40 foot but you would never make the turn at the end of the row if anyone else is in the park.

IN the northeast there are many older parks that have limitations on length of RV's. Same with state parks all around the country.
