The road is gravel to the top area. You can easily get to this part and park in the wide space. The road to the canyon below is steep and paved with deep potholes. I wouldn’t recommend a 5th wheel like yours down below.

Agree with Harbors light below. 5 th wheel below wouldn’t be great. There is a couple spots at end of pavement you would be fine. You can also get turned around there. Pavement has huge pot holes but are avoidable
