The road into Bread Rocks isn't too bad, but once you cross the cattle guards to turn in, there are some deep pot holes and trenches. I would not attempt it without a high clearance vehicle.

About 3 miles of well graded gravel road Shouldn't have any problem

We took our 25' motorhome (Winnebago Via) there without an issue. There is a main camping area that can accommodate several campers. Stop there. I would not advise going further on the dirt roads that parallel the mountains. Rutted and uneven.

It's about 3 miles of dirt road from Apache Pass road to the cattle guard. All of it can be washboard, just depends when it was last graded. Your vehicle could easily drive that road with a 7" clearance, but most likely you will be on washboard the whole way. Just past the cattle guard is a picnic area that does not allow camping, but saw people camped there. Just beyond the picnic area on the left is a large area where several people camped. We didn't like being on top of other campers, so would not stay there. We moved further up the road. From what you're describing, you would not want to venture any further and getting over/around the cattle guard, may not be your thing either. There are one or two sites before the cattle guard, but again, you may need to climb over a lip on the dirt road to access. Your other option would be to drive to the cattle, park on the road (it's wide enough) and then walk in and see if your rig could handle. We saw people doing that. Because further up that road beyond the cattle guard is a wide spot on the right that can accommodate several rigs.

As I recall it is several miles of relatively hard packed unpaved road before you reach the turnoff for Indian Bread Rocks. There wasn’t much washboard there. I saw 2 big diesel pushers camped there when I was there in the spring so they did not seem to have a problem navigating the roads.

This portion of the road between Apache Pass Road and the entrance of the recreation area is unpaved and about 3 miles long. We had no trouble at all in our 22' 2WD Sprinter Van about a year ago. No washboard at that time. Once inside the recreation area the road gets worse the farther you drive but there are numerous pullouts to camp.

We have the same vehicle and it was smooth driving in. The dirt road was in grreat shape. We camped close to the bread rocks entry for scenery purposes but it was closest to the dirt road transition so we didn't have to do much dirt driving.

It's not too far off the paved road. Unpaved portion def not of the washboard variety, smooth but unpaved. No prob in the van. We have a Promaster with the same clearance, no issues. Worth the stop.

The road to the site is good, about 4 miles of well graded dirt/gravel. At the end of the road though it's a tight turn off the last cattle guard, with several 12-18" deep ruts in the turn. This portion requires a high-clearance truck and trailer. There is no turn-around at the end of the road if you find it's too rough, so be prepared to back down a couple miles if necessary.

we drove in with a 41 foot 5th wheel with semi low clearance, no problem, just go slow!

In April 2022 it was pretty washboarded going back there but we made it in our Airstream which in clearance challenged as well. No issues at all, just took it nice and slow.

You may want to seek other accommodations. We would go back in a heartbeat with our 30 ft Airstream, but based on your criteria I suspect you would be more comfortable elsewhere.

Yes you’ll be okay and clearly visible where you’ll be able and not be able to make it :)
