Nice dispersed area, no neighbors and lots of space.  Almost zero road noise and close proximity to Grand Canyon South Rim Entrance made for a great stay!  We had no trouble getting our 39 foot Class A back there, but there is a decent little hill in the driveway that could cause a problem for a longer-wheelbase vehicle, so if you're in a bus-conversion 40+ feet long, I'd scout ahead.  You could probably use one of the sites closer to the road and avoid the little hill that we crossed, as an alternative.  We stayed a little further back (35.97408272506218,-111.80320237150028) and had the place to ourselves.

We recently spent 4 nights here, along with about 10-15 other camping vehicles, ranging from a Toyota Camry to 5th wheels and horse trailers.  Easy access for our 39ft class A and toad, but it was busy around 2pm when we arrived and filled up even more afterward.  Every day a few spots opened up by 10/11a but filled by 5p.  There were a couple of port-a-potties, if needed.  The camping site is actually bumpier than the gravel road coming in. Not much noise, considering proximity to highway and other campers, surprisingly.

We stayed recently when it was 116 during the day, but since the sites had electric, we gave it a shot.  The first two sites we tried had bad electrical setups. The breakers wouldn't lock in place, and kept flipping back to the tripped/open state.  No problem, since we were the only people there - we just notified management and moved sites.  They have water/sewer too, but you'll want to filter the water because of the taste.  The pool across the street was actually cold at night, even though the air temp was 90, so that was great.  

The "saloon" was being renovated and had a limited menu… I'll just say that we wished we had just grabbed some pre-packaged sandwiches from the general store instead.

Not a bad stop for staying in the park, with easy access to supplies, if neeeded.

Large, paved parking lot. Plenty of room for big rigs and vault toilets.  Some road noise, but nothing that bothered us. Great location for access to Glacier NP and a small town with a few restaurants was not far away.

Huge thanks to Rogue Snowmobilers - there was Wi-Fi available while we were there, which helped out a lot!

This is a large, paved parking lot with a stream nearby.  Has a good view of Mt. Hood and vault toilets, so that's a positive.  The downside is that it's not level.  Trailers shouldn't have a problem, but even with several blocks under our tires, our 39ft Class A was still  un-level.

This is my favorite dispersed site so far. Plenty of room for larger rigs, very close to a river and lots of woods to explore nearby.  Close enough to Mt. Rainier NP and nearby towns for supplies.   Vault toilets if needed, and the airstrip was only used twice in the 4 nights we stayed, i think (heard one mid-day, and saw another late morning).  

There is a single-lane bridge when turning in that could be tricky for a motorhome that is towing, but not enough traffic to cause us any issues getting in. For larger rigs - take the second left (at a Y-intersection, and then keep to the left and you won't have any trouble getting in. Going to the right at the Y takes you to an area that big rigs might have trouble finding spots or turning around, but still doable.

Easy to get to, plenty of room and quiet.  One of the best spots we've stayed in. Vault toilets across the highway if needed.

We stayed here for 1 night recently.  The site itself was fine, though there was a bunch of trash all over. Enough room for our 39ft rig and toad.  The road getting back to it was so twisty and tight that we scratched up the side of our rig. On the way out, we laid our outdoor rug on the bushes to keep from scratching again, so it is possible to get back here, but be prepared to work around that obstacle. 

Also, there is a sign at the entrance warning that the area is used for "rodeo livestock" grazing, and to be cautious around them and not to approach them. We never saw or heard them, but it's something to be aware of.

I'm not sure why there isn't a camp location in TD for these two sites, but they are directly off of a single lane, paved road in the same area as the others.  These are the only sites I could get our rig to.  There is a brown sign on the side of the Hwy 9 that points to a historical marker, if i recall correctly, that you can use as a marker.  We have a 39ft Class A and had no trouble getting setup. Plenty of room, a fire ring and great views in the background. It's definitely dusty, but that is my only complaint. Close enough to Hurricane and Springdale to get any supplies you need, too.

This is a really nice area for camping on the side of the road here, but we only could've squeezed our 39ft Class A into maybe 2 of these spots.  Usually when a dispersed site is marked Big Rig Friendly, we'll find that there is a large paved or gravel area for us to pull into and setup before you get to dirt road or off-road sites. There is a large paved area at this location, but we received a warning citation the next day, stating that we weren't allowed to camp there.  It's confusing because this is the exact same setup as any other "snow play" or "sno-park" areas that have allowed camping in the gravel or paved areas area. 

The paved area does have a couple of small stakes that say "no camping", but in our past dispersed camping experiences, those were used to mark areas where tents and vehicles couldn't pull off-road to camp.  Apparently those stakes refer to the paved area in this case?  There wasn't any reasoning provided on our citation, other than "find another area to camp."

We just spent the last three nights across the street from this location. There are a few spots for large RVs at this loop, but if it's full, you can go about 100 yards past this loop and across the street to this location (48.0512793, -124.1110441) and there's a lot of room in a large gravel area that is perfect for buses and coaches. We were about to settle for a muddy spot in this loop but luckily we scouted ahead with the toad and found the area across the street. Not as wooded and pretty as the loop area but plenty of level space still available.

I usually only stay at the places identified as "Big Rig Friendly" but I gave this location a shot since a review said there were buses that found a spot… we tried it in our 40ft Class A and got pretty jammed up down a narrow road, trying to follow the directions in the comment. Disconnected the toad and ran around trying to find anything that would work but there was nothing for our size. I do not recommend trying if you're in a large Class A.
