Usually stay at Oasis or Las Vegas RV Resort (Oasis $$$$, LVRVR inexpensive). Late Dec and Jan is way too cold....occasionally below 32. Great place in Nov & Mar.
Yes we have we stayed at the Oasis RV resort, really liked it. Does get cold at night though. it's pretty close to everything easy access to 15 and the strip. Close to Red rocksots to do Really liked the dry climate.
