Is primitive camping allowed near the Canyons? From what I can find on-line it looks like it would be. We'd prefer to boondock with the Pop-up if possible.
I don't know what route you plan but Mesquite Springs is our favorite CG in the park. The RV sites are really big and spread out from each other.
We have done the touristy thing in DV a few times. A couple of things you might miss:
I recommend taking a trip down West side road to Eagle Borax works if you have time. We have never gone further south than that but it looks like it's just another dirt road. The cool part is the North end of the road, especially if there is water. This is from 2005 when they had the 100 year bloom
If you leave via Salisbury Pass to the South check out the Amargosa Opera House. The China Ranch date farm is also an interesting side trip.
