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."
